Solution

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