Adenosine triphosphate (ATP) is a cell's energy currency. All of the following statements about ATP are true, except ATP is used to lower activation energy in enzymatic reactions.
- A) ATP is used to lower the activation energy in enzymatic reactions.
<h3>How does ATP affect enzyme activity?</h3>
Enzymes allow chemical reactions to proceed with activation energy provided by the catabolism of ATP.

Without enzymes, this would not be possible.
