Which is Not True About Enzymes

Question

Which is not true about enzymes?
A)Enzymes are found in all cells.
B)Enzymes are catalysts.
C)Enzymes participate in the cell's chemical reactions.
D)Enzymes can be denatured by heat and other agents.
E)Enzymes have high-energy bonds between phosphates.

Accepted Answer

Enzymes do not have high-energy bonds between phosphates. This is a characteristic of molecules such as ATP (adenosine triphosphate) which is used as a source of energy in cells. Enzymes, on the other hand, facilitate chemical reactions by lowering the activation energy required for the reaction to occur.
