Laboratory 2 Report: Enzyme Catakysis 1. Title • The effect that temperature, pH, time, enzyme concentration, and substrate concentration has on Enzyme Catalysis. 2. Abstract • Assess the general functions and activities of enzymes. Analyze the relationship between the structure and function of enzymes. Understand the concept of initial reaction rates of enzymes. Change the temperature, pH, enzyme concentration, substrate concentration, and time and record the effects of the enzyme catalysis. Explain how environmental factors affect the rate of enzyme-catalyzed reaction. Explain why catalysis activity decreased over time. 3. Introduction • An enzyme is a specific organic catalyst (substance that speeds up reaction without being used up in the experiment) in which it binds on to a specific substrate (reactant) at the active site and lowers the activation energy required to perform that reaction. Enzymes are important biologically because, for example, the human body performs certain reactions that keep us alive and most of them react at 37 degrees Celsius (body temperature. In each of these reactions, there is an enzyme that catalyzes these reactions to lower the amount of energy needed to perform this reaction. If enzymes didn’t exist then body temperature wouldn’t be enough to perform any of these reactions properly. Enzymes have certain conditions in which it will work in. For instance, most enzymes react at certain temperatures (varies in each enzyme), most enzymes react from a pH of 6- 8, and react faster or slower according to the amount of substrate present. Altering temperature, pH level, and concentrations of enzyme and substrates may cause absolute no change to the activation energy in which the enzyme would have been denatured. In addition to these environmental factors, other molecules may react with an enzyme. These may have great to no effect on the enzymes. Those

    It was hypothesized that the growth and seed pod production in the standard plants would increase when less competitors were present and that growth would be more affected by competition than seed pod production would be. The data in Figure 1 and Figure 2 support this hypothesis; the standard plant grew the most when it was in a container alone and, on average, produced more seeds when no competitors were present (Figure 1). Though growth and seed pod production had similar trends, the difference in growth is higher between the single-plant treatment and the three-plant treatment than the difference in seed pod production between the two treatments. This implies that growth was affected more than seed pod production in the presence of competition. It is important to note that the data relating to the growth of the standard plant were statistically significant (t-test p-value = 0.0104), suggesting that competition affected these results. The data relating to the seed pod production were not statistically significant (t-test p-value = 0.317), meaning competition did not affect the…

    Enzymes are proteins that are involved in all the chemical processes in living things. As they are made of proteins they are affected by pH and temperature. Enzymes are catalysts; they speed up chemical reactions without being changed themselves. Digestive enzymes speed up the breakdown of large food molecules into smaller ones so that the blood can absorb them. Enzymes turn a large starch molecule into thousands of tiny glucose molecules. Enzymes end in 'ase'. There are thousands of enzymes in our body but each enzyme is only specialised to do one thing, for example carbohydraise enzymes digest carbohydrates, protease enzymes digest protein.…

    Enzymes are a protein serving as a catalyst, a chemical agent that changes the rate of the reaction without being consumed by the reaction. Enzymes are proteins made up of long chains of amino acids. These form complex shapes. The enzymes are individuals, like the different players on a ball team, they have different specific structures and jobs. As one ball player may be very tall and one short, the specific different shape of the active site on an enzyme is unique and prepares it to mix with a certain substrate. Without enzymes, the process of metabolism would be hopelessly slow. The reactant an enzyme acts on is referred to the enzyme 's substrate. The enzyme will combine with or to its substrate. While the two are joined, the substrate is converted to its product by catalytic action of the enzyme. There is an active site of the enzyme molecule which is a restricted region that actually attaches to the substrate. Usually the active site is formed by only a few of the enzyme 's amino acids, the rest is just the framework that reinforces the active site. In an enzymatic reaction, the substrate enters the active site then is held in place by weak bonds. Now the enzyme does its work and first changes shape so it can hold onto the substrate. Next the substrate is changed to its product, the product is released and the enzymes active site is ready and waiting for another molecule of substrate.…

    Enzyme catalysis was observed in order to analyze how changes in temperature, pH, enzyme concentration, and substrate concentration affected an enzyme-catalyzed reaction. This experiment analyzed the rate of enzyme-catalyzed reactions and observed the correlation between catalase activity and products formed. It was found out that the rate of an enzyme-catalyzed reaction starts off rapidly, decreases, and levels off or completely stops, and can be further affected by environmental factors, which play a crucial role in regulating enzymes and metabolic processes.…

    Enzymes are proteins that catalyze biological reactions. In biological entities, chemical reaction is involved in most of their metabolic processes. Chemical reactions have to overcome an activation energy for it to proceed. However, the higher the activation energy, the more energy is needed for that reaction to proceed. The body rather than produce that extra energy, opts to reduce the activation energy barrier the reactants have to overcome. One main reason they opt for this choice is that the extra energy needed for the reaction would be either too expensive for the body i.e. its ATP consumption or would be detrimental to the body if the energy is in form of heat. So enzymes are very important biological catalyst. Life would not exist for more complex multicellular organisms hadn’t it been for the role enzymes play…

    Different sequence of amino acid produces different structure of protein, which determines the property of protein, thus each kind of enzymes has its unique active site, which only fits to complementary – shaped substrate to form product. Because of the feature of active site, each kind of enzymes therefore is specific for a particular reaction. However, there are several factors affect the rate of enzyme reactions, they are temperature, pH, concentration of enzyme, concentration of substrate and inhibitors. High temperature and pH affects the structure of enzyme, irreversible denaturation occurs, the shape of active site is changed, enzymes therefore no longer function. The effect of the other factors is slowing down the rate of enzyme reactions, it depends on the concentration of those factors. Since enzymes are catalyst of chemical reactions, they are responsible to the activities of cells, and they determine the function of tissues and organs as well.…

    Enzymes are protein molecules, which serve to accelerate the chemical reactions of living cells (often by several orders of magnitude). Without enzymes, most biochemical reactions would be too slow to even carry out life processes. Enzymes display great specificity and are not permanently modified by their participation in reactions. Since they are not changed during the reactions, it is cost-effective to use them more than once. However, if the enzymes are in solution with the reactants and/or products it is difficult to separate them.…
