Answer 2

The correct option is- Temporary deficiency of oxygen in muscle cells.

• After doing heavy exercise, the oxygen becomes deficient in the muscle cells and the energy requirement of the muscle cells is increased.
• In this condition, the breakdown of glucose occurs anaerobically in the muscle cells i.e. in the limited supply of oxygen. This process results in the formation of lactic acid that causes muscle cramps.
• But, this is a temporary condition. As the supply of oxygen becomes normal in the muscle cells, they start respiring aerobically.
