Aci produced in a muscle during anaerobic respiration?
During anaerobic respiration, when the oxygen supply is insufficient to meet the energy demands of the muscle cells, glucose is broken down without the utilization of oxygen. This process results in the production of lactic acid as a byproduct. The accumulation of lactic acid in the muscle causes an acidic environment, leading to muscle fatigue and soreness.
The chemical equation for anaerobic respiration in muscle tissue is:
C6H12O6 (glucose) → 2C3H6O3 (lactic acid) + 2ATP (energy)
In the absence of sufficient oxygen, glucose is converted into lactic acid through a series of enzymatic reactions, and the generated ATP provides the energy required for muscular contraction. However, the buildup of lactic acid causes the pH level in the muscle to decrease, contributing to muscle fatigue and limiting the muscle's ability to continue performing at its full capacity.
To mitigate the effects of lactic acid accumulation, the body relies on aerobic respiration (in the presence of oxygen) to produce energy while removing lactic acid and restoring the pH balance in the muscle. However, during intense exercise or when oxygen supply is insufficient, the production of lactic acid can exceed the rate at which it can be removed, leading to muscle fatigue and the sensation of "burning" in the muscles.
