Which of the following statements about glycolysis is true?
A) Glycolysis results in the release of carbon dioxide.

D) Glycolysis occurs twice per glucose molecule.
E) Glycolysis breaks glucose down to two pyruvate molecules.

Question

Quizplus · Accepted Answer

Glycolysis is the metabolic pathway that breaks down glucose into two pyruvate molecules. It occurs in the cytoplasm of cells and is the first step in both aerobic and anaerobic respiration. Glycolysis does not release carbon dioxide and is not a cyclical reaction. While glycolysis does involve reduction reactions, other molecules besides glucose are also reduced. Finally, glycolysis occurs only once per glucose molecule.
