Question

B) A popular lab that can be performed by students

Answer 1

Answer:

Enzyme catalase is affected by high temperatures

Explanation:

Enzymes are organic catalysts which are protein in nature therefore they are sensitive to changes in temperature. Most enzymes have an optimum range of temperature between 35-40°c.

As temperature is increased, the optimum temperature is reached where the rate of reaction is maximum. When beef liver is boiled, hydrogen peroxide is not broken down because higher temperatures denature enzymes making them non effective.
