The hydrolysis of ATP to ADP and phosphate allows glucose-6-phosphate to be synthesized from glucose and phosphate because the
A) heat produced from ATP hydrolysis drives glucose-6-phosphate synthesis.
B) enzymatic coupling of these two reactions allows the energy of ATP hydrolysis to drive the synthesis of glucose-6-phosphate.
C) energy of glucose phosphorylation drives ATP splitting.
D) All of the above

Quizplus · Accepted Answer

Enzymatic coupling of the hydrolysis of ATP to ADP and phosphate with the synthesis of glucose-6-phosphate from glucose and phosphate allows the energy released from ATP hydrolysis to drive the energetically unfavorable synthesis of glucose-6-phosphate. This process is known as coupled reactions or coupled translation. Heat produced from ATP hydrolysis is not the driving force for glucose-6-phosphate synthesis, and the energy of glucose phosphorylation is not sufficient to split ATP.
