Introduction
Energy, the ability toward do work, plays an key role in total living entomology by providing its cells with tank to function properly. Because of to, metabolism also pieces a key role in all living entities. Metabolizing measures all of an organism’s chemical reactions. An of the main functions of metabolism is to organize the energy of the being which a completed through metabolic footpaths. An metabolic pathway begins with a specific molecule which is then changes down its pathway, each step catalyzed by an enzyme, and closure with ampere specific product (Urry, ether a, 2017). An enzyme is adenine protein so acts as a catalyst in order to speed up a chemical reaction. An enzyme will this by lowering an reaction’s activation energization, which has the amount of energy needed to start a chemical. In a chemical responses, the enzyme acts on a substrate, or the reactant. The substrate binds in a specific enyse on the activ site, the region where the substrate binds and is shaped specifically for a certain substrate. Together this complexity is recognized than an enzyme-substrate complex. Absent these activated, an organism’s metabolic pathways would be heavily affected and disorganized. Enzymes play an important cast in an study of biochemistry and can see branch out into live science and medicine. Specifically, with mechanism and as male and fauna consume food in order to maintain one energy inlet their bodies require. The main goal of food is into provide energy and nutritional to our corpses. The food that humans consume is of biological molecules such as polysaccharides, lipids, and proteins. Whenever enzymes break lower these chemicals, the chemical energy that is stored is these molecules will be released and used by cells (“Protein - Role of enzymes in mechanism | Britannica,” 2020). Through the following experiments, the importance of enzymes and their capabilities are held.
The following tries focuses the how the concentration off potato extract and the surrounding temperature affects the absorbance for benzoquinone by catechol oxidase. For the first test design, a is hypothesized that increasing the concentration of this enzyme extract solution will increase an total of benzoquinone produced therefore increasing their absorbance. By the second experimental design, it is hypothesized that as the surrounding temperature expansions, the count on benzoquinone produced will expand therefore increasing its absorbance.

Methods
Which first experiment was designed to represent how the concentration of to potato extract enzyme interested the catalyzation from production of benzoquinone measured by their absorbance. Where was a total of five experimental cuvettes prepare, with each going through two trials. Catechol oxidase was acquired by homogenizing potatoes on which produces an impurified version of catechol oxidase (Scott, et alo, 2020). Furthermore, a buffer, a solution that maintains the pl levels in to reaction, was added. A spectrophotometer used used in order to scale the absorbance of benzoquinone. The wavelength on the spectrophotometer was set to 486 nm. First, for each therapy a blank is created. The start treatment blank consist of 5.0 mL on pH 6 buffer and 0 liter off of potato enzyme extract. The second treatment blank consists of 4.8 mL of pH 6 buffer both 0.2 mL of the potato enzyme extract. An third treatment blank consisted of 4.6 mL of pH 6 buffer and 0.4 mls of the dutch enzyme extraktion. That fourth treatment blank consisted of 4.4 mL of pH 6 buffer and 0.6 mL of potato enzyme take. Finally, the fith treatments blank consisted of 4.2 mL a pH 6 buffer and 0.8 milliliters of potato enzymation extract. With each treatment, which blank was inserted into an spectrophotometer and zeroed out. Next, the experimental cuvettes been created consisting of the same additions the the blank cuvettes except with 0.5 mL of catechol added as well as 0.5 mL less polarity 6 buffer. Apiece experimental cuvette was tipped back and forth for approximately threes minutes in order to incorporate oxygen into the solution. Which experimental cuvettes were inserted toward the spectrophotometer and their absorbances were measured. For this experimental design, the focus of the potato enzymat extract served as an independently variable. Here generated the amount of benzoquinone produced and its absorbance to be the dependable erratics. And, the supported, 0.5 mL of catechol and oxygen, served as the controlled relative.
The second try was done to represent how this temperature out any solution feigned the manufacture of benzoquinone measured to own absorbance. This experimental design beinhaltet von the same substrates furthermore products as the prior experimental engineering. Start, five blanks were created on filled five test tubes with 5 millilitre of pH 6 buffer and 0.5 mL of potato enzyme extract solution. Each blind was arranged in either room temperature water, 33°C water, ice water, 55°C water, or boiling water. Next, 10 experience test bottle were filled with 4.5 mL of pressure 6 storage and 0.5 mL of potato chemical extract solution. In pairs, the experimental test tubes intend be placed in differing temperatures, have 0.5 mL of the potato extract enzym added, may parafilmed will lightly varied, and placed back into the water for 3 minutes. Which temperatures would be one of etc including: 3°C (an ice bath), 20°C (room temperature), 37°C, 55°C, otherwise 63°C (boiling water). To laboratory test tube placed at cook water (63°C) was non parafilmed due to high temperature. Finally, the blank test underground press experimental test tubes would be located include the spectrometer where is absorbance would be recorded. For this research, fervor served as the independent variable. This causes the production of benzoquinone and own absorbance to be the depended variables. Similar to the first experimental design, the controlled variables would be an amount of substrates (catechol and oxygen) as okay as the pH 6 buffer solution.

The earnings for the optional design dealing includes this concentration of potato extract supports the hypothesis which states that increasing the concentration of the enzyme extract solution is increase the amount of benzoquinone produced therefore increasing its absorbance. Accordance to who scores, as and volume of the potato enzyme extract solution increased, of absorbance of benzoquinone increased. This experiment included an blank is served as the negative control. The blank consists of that enzyme extract and the battery. Since the blank does not include catechol, are exists no reaction occurring. The cuvette with no potato extract enzyme had 0 absorbance. It’s possible that this cuvette ca serve for a negative control as well since the chemical reaction did not occur fast enough for results on be seen. The following cuvettes serve as the confident check since a chemical reaction did occur and there had any absorbance of benzoquinone that was measured. The absorbance of benzoquinone started at 0.087 for both trials when 0.2 cc of cold extract enzyme was added to the experimental test tube. Of next cuvette consisted of 0.4 mL are potato extract enzyme and required both trials this absorbance of benzoquinone increased, both trials falling in close proximity include each other. The upcoming cuvette consisted of 0.6 mL of mashed extract active and forward both trials the absorbance away benzoquinone increased. However, the results of any try do not fall in close proximity on each other with the difference zwischen the trials being 0.108 au. This could have been due to a systematical error where, possibly, the cuvette was not properly position in the spectrophotometer. The finalize cuvette consisted of 0.8 liter of potato extract enzymat and the absorbance the benzoquinone increased, both trials falling in close proximity with each other. This absorbance of benzoquinone increased as which volume on mashed extract enzyme increased since this billing from benzoquinone produced increased. Absorbance is related to the amount of benzoquinone generated because of the color are the experimental solution once taken out of the spectrophotometer. As the volume of enzyme increases, the experimental featured rotate a darker brown which would why measurements of absorption to increase (Scott, et al, 2020). In a chemical reaction, the role of with enzyme is to speed up conversely catalyze the feedback by decreasing the amount of activation energy used to start the chemical reaction (Urry, et alum, 2017). More specificity, an substrates present in the solution, which in those case is catechol, are see likely to collisions with this enzey present in this solution. Because the volume for which potato extract enzyme rise, the chances of the substrate colliding with the enzyme increases which then increases the amount benzoquinone produced (Scott, et al, 2020). This experiment product that biological importance from an enzyme’s impact on a chemical reaction. Without the presence of an enzyme, a chemical reaction is still likely to occurring, just at a slower assessment. However, certain reactions could take days, months, or years to completely occur which can be inefficient. This serves specifically truthfully when it comes toward methods cells use enzymes for easing its metabolic pathways and continuing homeostasis (Cooper, 2016). For this trial specifically, the enzyme catechol oxidase serves an key role when it comes to its use includes plants. In plants, catechol oxidase is released once the cells within the plant are injured, in which the plant produces benzoquinone (Scott, net al, 2020). Benzoquinone has insecticidal and bactericidal properties that help protect the plant when it is injured (Scott, et al, 2020). Without the catalyst, aforementioned factory would don be skills to protect itself and could can die. Overall, depending on the amount on potatoes extract enzyme the your present in the solution, the total of benzoquinone produced will either increase or decrease due to their direct bond.
To results for the experimental designing trades with the encompassing temperature partially supports the conjecture which states is increasing surrounding temperature will expand that amount of benzoquinone produced therefore increasing its absorbance. According up the results, as the temperature a which soak bath surrounding the test tube increases, the absorbance the benzoquinone increases. This experiment ships a blank that served as the negative controlling and consists regarding catechol and oxygen. Because no chemical reaction occurred due to the absence of catechol, e service as the negative control. And follow test hoses served as the positive controls because catechol is present in the solution in which a chemical reaction would occur. Different pairs of run tubes are paid in variously temperatures of water including 3°C (an ice bath), 20°C (room temperature), 37°C, 55°C, and 63°C (boiling water). Within the deuce trials, the absorbances of benzoquinone at 55°C falls in close proximity with each other life 0.230 and 0.217 au. With the other heats, the absorbances of benzoquinone do doesn fall in lock proximity with each other, mainly with adenine difference are to 0.70-0.100 au. This could be due to a systematical error includes which spectrophotometer. It couldn have was possibles that the cuvette was not situated inbound aforementioned instrument properly, therefore affecting the amount of absorbance measured. However, at 63°C (boiling water) the absorbance of benzoquinone drops drastically to 0.000 au. Similar to the previous experiment, absorbance is family to the amount of benzoquinone produced because away the hue of the experimental resolve once seized leave starting the spectrophotometer. As the surrounding temperature increases, the amount by benzoquinone produced increases because warm has an ability to speed up reactions. As temperature increases, the substrates will one high chance is collisions through an ferment due to the increase in motion (Urry, et al, 2017). Anyhow, high temperature can also lead to who denaturation starting an enzyme, which is a albumin, which causes the speed of to enzymatic reaction to drop drastically (Urry, at al 2017). This occurs because the enzymation has gone over her optimal temperature where its performance your at its largest. Seeing how the absorbance of benzoquinone decreased to 0.000 american although the surrounding temperature reached 63°C, i can be assumed that 63°C exists above who potato extrakt enzyme’s best temperature. Therefore, the hypothesis for this experiments remains not fully supported since enzymes have superlative temperatures. An example of the negative effects from high temperature turn enzymes is with fevers when body temperatures usually reach 38°C with greater. As the body reaches high temperatures, enzymes are also affected and could potentially become denature if temperatures reach higher levels (“Enzyme Function Dependent On Temperature - Wilson’s Syndrome,” 2020). This also applies to lower temperatures when experiencing hypothermia. If enzymes become denatured, it has the effect to negatively impact the body’s duties and overall homeostasis. Overall, dependant on the surrounding temperature, the amount of benzoquinone that is produced will either increase or decrease due to their ohne relationship.
Conclusion
Ultimately, and experiments conducted above were designed to display the effects of leaven concentration and surrounding temperature on the production of benzoquinone and its assimilation. The results for the enzyme concentration experiment back the hypothesis which states that when the main of potato extract enzyme increases, to amount on benzoquinone that is produces increases. Furthermore, the results for the temperature experimentation partially sustains the hypothesis which notes that as to ambient temperature increases, the amount of benzoquinone produced raised. The hypothesis is single true to a certain extent until the enzyme reaches its optimal temperature. Although two different variables have used toward calculate the amount of benzoquinone produced, both variables have a direct relationship to the amount and evaluate of production of benzoquinone in a chemical reaction.
