Question

Naren was participating in a marathon. He was running at position two, right from the beginning. Just

when he was nearing the finishing line, he started running even faster so as to stand first. And when he

was about to win the marathon, he got a severe muscle cramp in his leg. This cramp prevented Naren

from running any further and shattered his dream of winning the marathon.

1.2 The process which provides a little extra energy to Naren for running very fast towards the end of

race is:

(a) anaerobic respiration

(b) aerobic respiration

(c) breathing

(d) fermentation​

Answer 1

Answer:

a) anaerobic respiration

Explanation:

because-

anaerobic respiration means - glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.

And aerobic respiration means-

Aerobic respiration is a chemical reaction that transfers energy to cells. The waste products of aerobic respiration are carbon dioxide and water.
