The purpose of glycolysis is A) to produce citric acid. B) to liberate energy from glucose. C) to produce large numbers of ATP. D) to trap energy in FADH₂. E) none of these answers.

Question

Quizplus · Accepted Answer

Glycolysis is the process by which glucose is broken down into two molecules of pyruvate, generating a small amount of ATP and NADH. The primary purpose of glycolysis is to liberate energy from glucose in the form of ATP. A, C, D, and E are incorrect: A) Citric acid is produced in the citric acid cycle (also known as the Krebs cycle). C) A large number of ATP molecules are produced through oxidative phosphorylation, which occurs after glycolysis and the citric acid cycle. D) FADH2 (not "FADH₂") is a molecule involved in the electron transport chain, which generates ATP through oxidative phosphorylation after glycolysis and the citric acid cycle. E) This answer is too vague and does not provide any information about the purpose of glycolysis.
