Multiple Choice
Which of the following is a product of glycolysis (per one molecule of glucose)?
A
Citrate
B
Oxaloacetate
C
Pyruvate
D
Acetyl-CoA
Verified step by step guidance1
Understand that glycolysis is the metabolic pathway that breaks down one molecule of glucose (a 6-carbon sugar) into two molecules of pyruvate (each with 3 carbons).
Recall the main products of glycolysis: 2 molecules of pyruvate, 2 molecules of ATP (net gain), and 2 molecules of NADH per glucose molecule.
Recognize that citrate and oxaloacetate are intermediates in the citric acid cycle (Krebs cycle), which occurs after glycolysis, not products of glycolysis itself.
Know that acetyl-CoA is formed from pyruvate during the link reaction (pyruvate decarboxylation) before entering the citric acid cycle, so it is not a direct product of glycolysis.
Therefore, identify pyruvate as the direct product of glycolysis per one molecule of glucose.
