The correct answer is option (h) the breathing rate to supply more oxygen to cells for the release of energy.
Breathing refers to the process of inhaling oxygen and exhaling carbon dioxide from the lungs. A normal breathing rate at rest is around 15 breathes per minute which is significantly increased to 40 -50 breathes per minute during vigorous activity or excercise.
During exercise, the breathing rate, pulse rate and lactic acid levels increase in the human body. Muscle cells have an increased need for energy and heart pumps more oxygen to the muscle cells to meet the requirement. Breathing rate increases to supply more oxygen to the muscle cells which is required for the oxidation of the glucose, release of more energy and to get rid of the carbon dioxide.
