Question

"Which molecule controls the rate of pentose phosphate pathway?

A. NaDP+/NaDPH
B. ribose-5-phosphate
C. glucose D. ADP/ATP E.NAD+/NADH

Which reaction is influenced by the molecule in part A? Choose the enzyme that catalyzes the reaction.

A. lactonose
B. transketolase
C. phosphopentose isomerase
D. transaldose
E. phosphopentose epimerase
F. glucose 6-phosphate dehydrogenase"

Answer 1

Answer:

Part 1:

Correct option is A: "NaDP+/NaDPH"

Part 2:

Correct option is F: "glucose 6-phosphate dehydrogenase"

Explanation:

Various levels of control are put in place to keep a check on the pathway. This is an example of one such control. This dehydrogenase enzyme is responsible to control the rate of reaction and it is stimulated by NADP+ while it is inhibited by NaDPH. The oxidative reaction is under the influence of the NaDP+/NaDPH concentration, which is catalyzed by glucose 6-phosphate dehydrogenase.
