Which of the following metabolic pathways can proceed in the absence of oxygen? A) glycolysis B) oxidative phosphorylation C) Krebs cycle D) the breakdown of fatty acids to CO₂ and H₂O E) None of the choices are correct.

Question

Quizplus · Accepted Answer

Glycolysis is an anaerobic metabolic pathway that can occur in the absence of oxygen. It breaks down glucose into pyruvate and produces a small amount of ATP. While oxidative phosphorylation and the Krebs cycle require oxygen, the breakdown of fatty acids to CO2 and H2O can occur in the presence of oxygen, but not in its absence.
