Is there oxygen in glycolysis?

In glycolysis, a 2 ATP investment results in a 4 ATP payoff. Unlike the rest of aerobic respiration, which takes place in the mitochondria, glycolysis takes place in the cytoplasm of the cell. Unlike the rest of aerobic respiration, glycolysis does not require oxygen.

Similarly, it is asked, is glycolysis anaerobic?

Glycolysis, as we have just described it, is an anaerobic process. None of its nine steps involve the use of oxygen. However, immediately upon finishing glycolysis, the cell must continue respiration in either an aerobic or anaerobic direction; this choice is made based on the circumstances of the particular cell.

Why is more ATP made from glucose in the presence of oxygen?

when oxygen is not available, the krebs cycle and electron transport cannot proceed, and glycolysis produces just 2 ATP molecules per glucose molecule. Under aerobic conditions, the Krebs cycle and electron transport enable the cell to produce 34 more ATP molecules per glucose molecule.

What happens to the citric acid cycle without oxygen?

The electron carriers NADH and FADH are sent to the final step of cell respiration, which is respiratory electron transport. The Krebs cycle does not use oxygen, though it does stop in the absence of oxygen because it runs out of NAD and FAD.
