Which of the following statements is true of the glycolytic pathway?
A) Each reaction in the glycolytic pathway is catalyzed by a single enzyme, acetyl CoA dehydrogenase.
B) In each reaction in the pathway, one molecule of ATP is hydrolyzed for each molecule of glucose that is metabolized.
C) In each reaction in the glycolytic pathway, two NADP molecules are released that make coupled exergonic reactions possible.
D) Each reaction has a net gain of three ATP molecules for each glucose molecule processed in glycolysis.

Quizplus · Accepted Answer

Glycolysis involves the hydrolysis of one molecule of ATP for each molecule of glucose metabolized, particularly in the initial steps where glucose is phosphorylated to glucose-6-phosphate and then fructose-6-phosphate is phosphorylated to fructose-1,6-bisphosphate. This investment of ATP is crucial for the pathway to proceed and ultimately results in a net gain of ATP.
