Yes, pyruvate oxidation requires oxygen to occur.
Cellular respiration is the process that cells use to extract energy from food. It consists of four main stages. According to the reference material, while glycolysis can occur without oxygen through fermentation, the subsequent stages: pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation, all require oxygen.
Here's a breakdown:
- Glycolysis: Can occur without oxygen (anaerobic)
- Pyruvate Oxidation: Requires oxygen (aerobic)
- Citric Acid Cycle: Requires oxygen (aerobic)
- Oxidative Phosphorylation: Requires oxygen (aerobic)
Therefore, the process of pyruvate oxidation is dependent on the presence of oxygen.
