1.Glucose 6-phosphatase (G6Pase) catalyzes the dephosphorylationof glucose 6-phosphate (G6P). It bypasses the irreversibleglycolytic reaction of glucokinase. Select the best answer thatexplains why G6Pase does not catalyze the reverse reaction ofglucokinase.
A. G6Pase catalyzes an endergonic reaction
B. G6Pase hydrolyzes G6P
C. G6Pase requires energy from ATP to dephosphorylate G6P
D. G6Pase requires only one substrate
5. Insulin and glucagon oppositely control glucose metabolism inthe liver. The former is elevated in response to a carbohydratemeal (fed state) and the latter in response to fasting. Show theoverall effect of each on the pathways of glucose metabolism.
