Enzymes Are

Question

Enzymes are
A)broken down in reactions that require energy input.
B)proteins that function as catalysts.
C)used up in chemical reactions.
D)not needed for catabolic reactions.
E)All of these choices are correct.

Accepted Answer

Enzymes are proteins that function as catalysts in chemical reactions. They lower the activation energy required for the reaction to occur, increasing the rate of the reaction, but they are not used up or broken down in the process. Additionally, enzymes can be involved in both catabolic and anabolic reactions.
