Today we'll cover the key principles of cellular respiration. The process occurs in three main stages: glycolysis, the Krebs cycle, and oxidative phosphorylation.
Glycolysis is the first stage and occurs in the cytoplasm. It breaks down one molecule of glucose into two molecules of pyruvate, producing a net gain of 2 ATP.
How does glycolysis differ from the other two stages in terms of oxygen requirements?
Great question. Glycolysis is anaerobic. It doesn't require oxygen. The Krebs cycle and oxidative phosphorylation are aerobic and take place inside the mitochondria.
Could you recommend any additional reading on the electron transport chain?
