unlike aerobic respiration, anaerobic fermentation may occur under which of the following conditions?\nwhen no oxygen is available\nwhen no glucose is available\nwhen no pyruvate is available\nwhen no adp is available
Answer
Brief Explanations:
Aerobic respiration requires oxygen, while anaerobic fermentation occurs in the absence of oxygen. Glucose is needed for both processes as a starting - point for energy production. Pyruvate is an intermediate product in both. ADP is involved in energy transfer in both. So the key difference is the presence or absence of oxygen.
Answer:
When no oxygen is available
