Question

why do we do anaerobic respiration during strenuous physical exercise​

Answer 1

Answer:

Anaerobic respiration happens in muscles during hard exercise. Glucose is not completely broken down, so less energy is released than during aerobic respiration. There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.
