Web12 de jan. de 2016 · Catalase is an enzyme found in all organisms that breathe oxygen. This enzyme facilitates the decomposition of hydrogen peroxide (a toxic by-product of the body) into water and oxygen. Catalase... WebIn conclusion, I can say that as the pH increases, so does the rate of reaction meaning that the enzyme activity increases. Then at pH7, the enzyme activity is at its maximum and …
WebPART D – What is the Effect of pH on Catalase Activity? Place 1 pipette-full of normal hydrogen peroxide in a clean test tube. Collect a piece of liver from the beaker labeled PART D ACID. Add the piece of liver to the test tube and record the reaction rate. Place 1 pipette-full of normal hydrogen peroxide in a clean test tube. WebThis was achieved by using a test tube rack and tongs to handle the apparatus so that the heat from my hands did not affect the Catalase. pH – Any change in pH affects the ionic and hydrogen bonding in an enzyme and so alters it shape. Each enzyme has an optimum pH at which its active site best fits the substrate.
WebWhen the enzyme catalase comes into contact with its substrate, hydrogen peroxide, it starts breaking it down into water and oxygen. Oxygen is a gas and therefore wants to escape the liquid.
