Answer:
A. It decreases the activation energy needed to start the reaction.
Explanation:
Catalase is an enzyme found in the cells of organisms exposed to aerobic conditions. It is an enzyme that catalyses the breakdown or decomposition of hydrogen peroxide in the liver to water (H2O) and oxygen (O2).
Catalase, like every other enzyme, operates by binding to the substrate, which in this case is hydrogen peroxide. Catalase then REDUCES or LOWERS the ACTIVATION ENERGY needed to start the reaction.
