Can glycolysis occur in the presence of oxygen?

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.

Furthermore, what is glycolysis without oxygen?

Respiration is the process of making ATP rather than breaking it down. Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration does not use oxygen. Both types of cell respiration begin with the process of glycolysis, after which the two diverge.

How can glycolysis occur without oxygen?

Glycolysis can occur with or without oxygen. In the presence of oxygen, glycolysis is the first stage of aerobic cellular respiration. Without oxygen, glycolysis allows cells to make small amounts of ATP. This process is called anaerobic respiration or fermentation.

Why is glycolysis considered to be 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.
