Question

In a chemical reaction in a living system, enzymes are used as catalysts. Which of the following statements about enzymes is incorrect?A. Enzymes increase the energy of activation necessary for a chemical reaction to go forward. B. Enzymes enter reactions and can be reused. C. Enzymes reduce the energy of activation necessary for a chemical reaction to go forward. D. Enzymes are sometimes referred to as biological catalysts; however, not all biological catalysts are proteins.E. Enzymes speed up chemical reactions in living systems.

Answer 1

A is incorrect.

Enzymes speed up/assist in chemical reactions by DECREASING the activation energy needed for a reaction. This is what C is saying.

Answer 2

C. Enzymes increase the energy of activation necessary for a chemical reaction to go forward.

Instead Enzymes reduce the energy of activation, which means they reduce the amount of energy the reaction needs to start, so it can start faster
