Answer» 1. Athletes felt muscular pain is due to the inadequacy of O2. In the absence of O2 partial oxidation takes place. It involves the formation of pyruvic acid followed by lactic acid. 2. Yeast & Lactobacillus. 3. After the formation of pyruvic acid, 2 NADPH molecules are utilised for the formation of Lactic acid. So the net gain of ATP in Anaerobic respiration is 2 ATPs. |
