Which of the following is not true of an en-

zyme? An enzyme

a. is a protein.

b. acts as a biological catalyst.

c. supplies energy to start a chemical reaction.

d. is specific.

e. lowers the energy barrier for a chemical

reaction.

I believe it is C, because they lower the need for energy but don't provide it

B. Enzymes act as a biological catalyst as they significantly speed up the rate of virtually all chemical reactions that take place within cells. Enzymes are highly specific and each enzyme will only support one type of reaction. Enzymes are a form of proteins. Therefore, C is incorrect. They definitely don't supply energy to start a chemical reaction.
