The phosphorylation of glucose to glucose 6-phosphate
A) is so strongly exergonic that it does not require a catalyst.
B) is an exergonic reaction not coupled to any other reaction.
C) is an endergonic reaction that takes place because it is coupled to the exergonic hydrolysis of ATP.
D) is an exergonic reaction that is coupled to the endergonic hydrolysis of ATP.

Question

Quizplus · Accepted Answer

The phosphorylation of glucose to glucose 6-phosphate is an endergonic reaction, meaning it requires energy to proceed. It occurs because it is coupled to the exergonic (energy-releasing) hydrolysis of ATP, which provides the necessary energy to drive the reaction forward.
