Question

How does the human body cope with an increased need for energy during exercise?a: it shuts downb:it decreses the heart ratec:it releases sweat to cool downd: it decreases the breathing rate

Answer 1

The correct answer is: it releases sweat to cool down.

During the exercise, body temperature increases and as a result respiration releases energy in the muscles, the skin produces sweat, which evaporates from the surface of the skin. Evaporation takes heat energy from the body.

Energy needed to perform exercise is derived from anaerobic metabolism within the cytosol of muscle cells (anaerobic respiration).
