Answer Key / Explanation : (d) -

(d)

The ATP is actively and continuously replenished by energy rich muscle phosphogen, In muscles, the pyruvic acid produced by glycolysis  is transformed into lactic acid in absence of oxygen. Accumulation of lactic acid in the muscle causes fatigue. In the liver, 80% of lactic acid resynthesized  by a process called Cori’s cycle.
