Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Oxygen combines with digested food molecules in body cells to release the energy stored in them. This process is called ____ .

A	respiration
B	breathing
C	digestion
D	None of the above

Explanation:

Detailed explanation-1: -cellular respiration, the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Detailed explanation-2: -Respiration is the energy-releasing process. In this processed food is oxidized for the generation of energy. It is also called cellular respiration. The energy is produced in form of ATP.

Detailed explanation-3: -Cellular respiration can be defined generally as the process by which chemical energy is released during the oxidation of organic molecules. If it requires oxygen it is called aerobic respiration, whereas if it takes place in the absence of oxygen it is anaerobic respiration.
