Enzymes and Metabolic Rates

Introduction Enzymes are catalysts that speed up chemical reactions without being consumed or changed themselves. Each enzyme has a substrate that will match perfectly, almost as if it is a lock and key fit. If the substrate does not fit the enzyme only partial to no function will occur. Each enzyme is formed of polypeptide chains that wind and bend to form complex grooves and valleys. These grooves are the active sites. The active site is where the substrate will fit perfectly. Certain things can change or denature, or breakdown, an enzyme. Some of these factors include variations of pH levels, temperature, and the presence of inhibitors. These factors can be detrimental to an enzyme and cause it to become denatured.

The neutral pH and room temperature tubes produced the most foam. This is because the enzyme is most reactive at these points. pH 7 is like water being added to the solution, the other pH levels are too acidic or too basic for the enzyme. Room temperature involves the enzyme in its natural state. When the pH level is too acidic/basic or when the temperature is too cold/hot the enzyme begins to denature, or breakdown. This causes the reaction to be slowed down or even stopped completely.
Discussion
In conclusion, the pH and temperature that most closely mocked the enzyme in its natural state were the most reactive. This is because the enzyme is not denatured and acts as it should. The hypothesis; if the pH and/or temperature are altered then the enzyme will become denatured, but if the temperature and/pH remain at normal levels (i.e. room temperature, or pH level 7) the enzyme will remain intact and function properly; was proven through this experiment. This result was expected because it is the “neutral” aspects of the experiment. If this experiment were done again all aspects would remain the same. This experiment was successful in proving the hypothesis

    Denaturation is the process whereby the shape of the protein is disrupted, leading to the change in chemical and physical properties of the properties. In some cases, there may also be some loss of biological activity. However, the primary structure will not be disrupted when a protein denature as a large amount of energy is needed to break down the relatively strong peptide bonds in the primary structure. Some of the factors resulting in the denaturation of proteins are heat and change in pH or potential of hydrogen. An increase in temperature will disrupt the weak forces of attraction between the R groups such as hydrogen bonds, Van der Waales forces and induced dipole-induced dipole attractions.…

    If the temperature is too hot or if the pH is not at the optimal value, the enzymes will begin to break down and they won’t work anymore. This process is called denaturing. The question “How does substrate concentration and pH affect enzyme function” was posed to the students. We then hypothesized that there will be an optimal condition for where the enzyme would work best, and outside these conditions the functioning of the enzyme would be lower. I predict that 3% H2O2 will be the in the optimal zone for substrate concentration, and that pH5 will also be in the optimal zone.…

    1) Important solubility characteristics for a solvent to be used in the crystallization of an organic solid that’s contaminated with impurities is that the organic solid should have low solubility at low temperatures in the solvent, but highly soluble at high temperatures. Also, the solvent should allow the impurities to be either completely soluble or completely insoluble at all temperatures. 2) One way to improve our percent recovery is by making a second crop of crystals by removing the solvent from the mother liquor, or crystallization filtrate, and then recrystallizing the resulting solid. One other way to minimize lost product is by placing our flask on a hot plate to preheat and keep it on there while the hot solution is being gravity…

    Introduction Catalysts speed up the rate of a reaction without being consumed in the process4. Enzymes are proteins that act as catalysts to a given biochemical reaction4. Enzymes manage to expedite metabolic reactions by lowering the activation energy required for the reaction to proceed4. In ideal conditions, the reactant macromolecule binds and acts on what is referred to as a substrate. However, enzymes require specific conditions specific conditions to perform most effectively4.…

    The trials range from almost melting point at 4oC (as a control) to 70oC. If the temperature is too low, there can be little to no noticeable reaction since the enzyme is operating below its optimal temperature, however if the temperature is well above the enzymes prime operating temperature, thermal deactivation or denaturation can occur (vlab.amrita.edu, 2012). This process modifies the molecular structure of a protein, it involves breaking weak links or bonds within a protein molecule that are responsible for the highly ordered structure of the protein in its native state. The consequence of this phenomenon is the loss of the catalytic ability of an enzyme, the enzyme is no longer a catalyst, so no reaction can occur. The denaturation of many proteins, including alpha and beta amylase is irreversible (Encyclopedia Britannica,…

    One sort of examples are the hydrolysis reactions of diarylmethyl halides. For illustration, the hydrolysis of diphenylmethyl chloride is discussed here. The reason for the dropping rate at the later period is that the leaving group having disassociated may compete with the reactant to combine with the diphenylmethyl cation. At the beginning, although chloride ion is a better nucleophilic reagent than water, its concentration is so small that it can be neglected, while the concentration of water is so large that it does not appear in the rate formula as the solvent. During the process of the reaction, the concentration of chloride ion increases gradually and the effect of the competition between chloride ion and water becomes important enough to be taken into consideration in the later period, so the rate drops later.…

    This is because catalase binds with the hydrogen peroxide substrate at its transition state to weaken the covalent bonds, reducing the energy and precision needed for a collision of water molecules to yield a reaction. In our cells, there are numerous naturally occurring reactions which produce hydrogen peroxide. However, hydrogen peroxide is a toxin to the human body. Although it naturally decomposes to oxygen and water, this reaction is slow. To…

    pH Levels: The pH level system is the measure of the concentration of hydrogen ions in solutions. Subsequently, if there is a higher concentration then the pH is low meaning it’s acidic and if there’s a lower concentration then there’s a high pH levels meaning it’s basic. pH levels affect the quality of water because it affects the toxicity and the solubility of chemical substances and heavy metals. This causes the concentration of hydrogen ions in the water to change from the normal pH range for water of 6.5 to 8.5. This change causes the water quality to diminish because more harmful chemicals are dissolved in the water releasing toxins.…

    Hydrochloric acid can therefore be used to prepare salts called chlorides, such as sodium chloride. Hydrochloric acid is a strong acid, due to its ability to completely dissociate in water. Monoprotic acids have one acid dissociation constant, Ka, which indicates the level of dissociation in water. For a strong acid like HCl, the Ka value is large. When chloride salts such as NaCl are added to aqueous HCl they have practically no effect on pH, indicating that Cl− is an extremely weak conjugate base and that HCl is fully dissociated in aqueous solution.…

    This enzyme can be found in many organisms such as, plants, bacteria, and fungi. Its duty is to break down hydrogen peroxide. Therefore, if there is an alteration to this enzyme that impedes it from doing so, the exceedingly toxic hydrogen peroxide will not be removed. Consequently, causing a cell to become damaged. Here, our main objective will be to determine the absorbance rates during each manipulation.…
