Question

Quizplus · Accepted Answer

Glycolysis is an anaerobic process, meaning it does not require oxygen. It is the breakdown of glucose into pyruvate, and can occur in tissues without sufficient oxygen availability such as during exercise. Glycolysis is not the breakdown of pyruvate to glucose (B), as this would be the reverse process. It is not the only source of ATP in muscle tissue (C), as there are other energy systems such as oxidative phosphorylation that can produce ATP. Glycolysis is not only active during rest (D), as it is a central process in energy production. Glycolysis also does not occur in the nucleus (E), as it occurs in the cytoplasm of the cell.
