उत्तर
- While exercising, the muscle cells perform anaerobic respiration.
- During anaerobic respiration in muscle cells, lactic acid accumulates in the body.
- Lactic acid accumulation is a result of the process of fermentation, during which glucose is broken down by anaerobic respiration, forming organic acids.
- Also, the production of ATP is comparatively less during anaerobic respiration.
Hence, we feel exhausted after exercising.
