Question

Which of the following is not a primary function of the products of the pentose phosphate pathway? a. To maintain levels of NADPH. b. To provide reducing power for the synthesis of fatty acids.c. To serve as precursors in the biosynthesis of RNA and DNA. d. To directly generate ATP

Answer 1

Answer: The correct answer is D.

Explanation:

As you can see in every step of the pathway, ATP is not generated directly. Although, in the oxidative phase, molecules of NADPH are produced and these can be used for synthesize ATP indirectly; the NADPH molecules are hihgly demanded in tissues that carry out constantly synthesis of fatty acids, such as liver.

Therefore the correct answer is D.
