Q.Assertion (A): During continued muscular activity, the glycogen breaks down in the presence of oxygen (within the body muscles) and releases energy along with the metabolites– lactic acid, CO2, heat and moisture. Reason (R): During continued muscular activity the O2 restricts the release of energy after some time as body muscles are involved in managing the metabolites. Codes :
Correct answer: (A) is true and (R) is false.
Explanation
During continued muscular activity, the body consumes fuel and gives out energy. The energy producing material in the muscle is mainly glycogen. In muscular work glycogen unites with oxygen in the blood stream, releases energy and form lactic acid and carbon dioxide both this waste product interfere with continued muscular activity of body.
