Question

Which of the following terms describes the role of ATP in this reaction? 
A) The hydrolysis of ATP is inhibiting this reaction. 
B) The hydrolysis of ATP is a catalyst for this reaction. 
C) The hydrolysis of ATP is regulating this reaction. 
D) The hydrolysis of ATP is coupled to this reaction. 
E) All of the above

Quizplus · Accepted Answer

The hydrolysis of ATP is coupled to this reaction, meaning that the energy released from the hydrolysis of ATP is necessary for the reaction to occur. Option A is incorrect because the hydrolysis of ATP is not inhibiting the reaction, but rather facilitating it. Option B is incorrect because while the hydrolysis of ATP does act as a catalyst for the reaction, it is not the only role of ATP in this reaction. Option C is also not the best choice because while the hydrolysis of ATP does play a regulatory role in some reactions, it is not necessarily the case for all reactions. Therefore, the best answer is D.
