Answer:
Explanation:
Exercise, during exercise, the oxygen in muscle converts available glucose into energy and heat which increases cell respiration. Exercise increases cellular respiration mainly in muscle cells and further prolonged exercise increase the number of mitochondria in muscle cells and it causes further increase the rate of cellular respiration. There is the increase of carbon dioxide production during exercise.
The activity best takes place during exercise - A. cell respiration increases
It includes the reactions in the cells of your body when they convert the food you eat into a molecule of energy in a form your cells can use. Energy is released in the form of ATP.
During exercise muscles work harder, your body uses more oxygen and produces more carbon dioxide. Oxygen is used in cellular respiration to generate energy for muscles to work.
