Detailed explanation-1: -Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Detailed explanation-2: -During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs. This is very similar to wood burning in a fire.
Detailed explanation-3: -Oxygen is used as the end electron acceptor for the electron transport chain in cellular respiration. It allows electrons to be transferred through the electron transport chain in order to create an electrochemical gradient for hydrogen to create ATP.
