Enzyme lab questions 1. How do you depict for the differences in rates? 1. In the first taste, 2 mL of H2O2 was mixed with 0.1g sand. In this mixture, on that point argon no enzymes present and because no products argon yeared. The reply rate was rated 0, bonnie as we anticipated. 2. The 2nd witness was a mixture of 2 mL H2O2 and 0.1g manganese dioxide. We poop use the same chief(prenominal) we used for the first examine, manganese dioxide is non a protein, not an enzyme, it is a catalyst. Due to this, no products are categoryed, and just as we anticipated, the reception rate was presumption a 0. 3. The 3rd try out is a mixture of 2 mL H2O2 and liver-colored-colored. In this situation, twain the substrate (H2O2) and the enzyme (catalase) are present, and whence the products, irrigate and oxygen are produced. Just as our array anticipated, the response rate would be fairly high, and by our observations, we gave the reception rate a 3. 4. The fourth mixture is composed of 2 mL H2O2 and a picayune portion of a potato. I anticipated that thither would be a reception, however, I knew that the answer rate would not be as high as the liver because the enzyme concentration in a potato should be lower than that of the liver. Through our observations, this investigate received a 2. 5.

The ordinal experiment contains liquid from experiment 3, the unexpended everyplace liver from experiment 3 and a fresh piece of liver. The reaction rate should be 0 because in the left oer liquid from experiment 3, there are only products and no substrates (this is because the enzyme in experiment 3 has already formed the products pee and oxygen from the H2O2). The new liver has enzymes, however, because there are no substrates, there can be no reaction to form products. From our observations, we gave the reaction rate a 0, like we anticipated. 6. Experiment 6 is a combination of left over liquid from experiment 3, liver used in experiment 3 and 1 mL H2O2. This experiment was through with(p) to show that enzymes may be reused...If you want to get a full essay, order it on our website: Ordercustompaper.com
