Question

Which of the following statements is correct about oxidative pentose phosphate pathway?

(a) It generates NADH

(b) It oxidizes NADPH to NADP^+

(c) The pathway supplies ribose 5-phosphate and NADPH in the quantities the cell requires

(d) Glucose 6-phosphatase catalyzes the rate limiting reaction of the pathway

This question was addressed to me in an internship interview.

The query is from Pentose Phosphate Pathway of Glucose Oxidation topic in section Principles of Bioenergetics and Glycolysis of Biochemistry

Answer 1

Correct answer is (c) The pathway supplies ribose 5-phosphate and NADPH in the quantities the cell requires

Best explanation: Oxidative pentose phosphate pathway supplies ribose 5-phosphate and NADPH in the quantities the cell requires. It reduces NADP^+ to NADPH.
