Does the Krebs cycle occur in anaerobic respiration?

No, the Krebs cycle, also known as the citric acid cycle or tricarboxylic acid (TCA) cycle, does not occur in anaerobic respiration. The Krebs cycle is an integral part of aerobic respiration, which takes place in the presence of oxygen. In anaerobic respiration, such as fermentation, the Krebs cycle does not occur. Instead, other processes specific to anaerobic conditions are involved in energy production.
