Detailed explanation-1: -Oxygen is used to breakdown glucose into carbon dioxide and water. The breakdown of glucose occurs in the cells of an organism.

Detailed explanation-2: -During cellular respiration, oxygen is utilized to break glucose into carbon dioxide, water and energy.

Detailed explanation-3: -This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. Breaking down sugar produces the energy your body needs.

Detailed explanation-4: -Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP . Generally speaking, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
