Question

Which one of the following statements about ATP hydrolysis is not correct?

A. ATP hydrolysis releases energy.
B. ATP hydrolysis results in the formation of ADP.
C. ATP hydrolysis is an endergonic reaction.
D. ATP hydrolysis powers cellular work.

Answer 1

The statement that is not correct about ATP hydrolysis is option C: ATP hydrolysis is an endergonic reaction.

Step-by-step explanation:

The statement that is not correct about ATP hydrolysis is option C: ATP hydrolysis is an endergonic reaction.

ATP hydrolysis is an exergonic reaction, meaning it releases energy. When ATP is hydrolyzed, it breaks down into ADP and inorganic phosphate, releasing energy that can be used for cellular work. This is shown in the equation: ATP + H₂O → ADP + Pi + 7.4 kcal/mol. Therefore, option C is the incorrect statement about ATP hydrolysis.
