Many of the enzymes of the Calvin cycle are also involved in ____; however, the glyceraldehyde-3-phosphate dehydrogenase of the Calvin cycle is specific for ____. A) glycolysis; NADPH B) citric acid cycle; NADH C) glycolysis; FADH₂ D) citric acid cycle, NADPH E) none of the above

Question

Quizplus · Accepted Answer

Many of the enzymes of the Calvin cycle are also involved in glycolysis for the conversion of glucose to pyruvate. However, the enzyme glyceraldehyde-3-phosphate dehydrogenase in the Calvin cycle is specific for NADPH, which is used in the biosynthesis of organic molecules. Thus, option A is the correct choice. Option B is incorrect because the citric acid cycle requires the use of NADH, not NADPH. Option C is incorrect because FADH₂ is not a recognized molecule in any metabolic pathway. Option D is incorrect because NADPH is not used in the citric acid cycle. Option E is incorrect because there is a clear answer for this question.
