4. 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.

9. 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 reactionspossible.(D)Each reaction has a net gain of three ATP molecules for each glucose molecule processed in glycolysis.
