Question

Several molecules are produced as a result of glycolysis.

What is the net production of ATP, pyruvate, and NADH when one molecule of glucose undergoes glycolysis?

Choose 1 answer:


A. 2 ATP, 2 NADH, and 2 pyruvate

B. 4 ATP, 1 NADH, 2 pyruvate

C. 4 ATP, 2 NADH, and 4 pyruvate

D. 2 ATP, 1 NADH, and 1 pyruvate

Answer 1

The correct answer is 2 ATP, 2 NADH, 2 pyruvate.

Glycolysis will produce 2 NADH (reducing agents) from the 6th reaction involving the conversion of glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate by the enzyme glyceraldehyde-3-phosphate dehydrogenase. 2 ATP and 2 pyruvate is yielded by the last reaction of glycolysis which is the conversion of phosphoenolpyruvate to pyruvate by the enzyme pyruvate kinase.
