During metabolism, the complete breakdown of one molecule of glucose results in a maximum yield of 38 molecules of ATP.
The major reason why glucose is broken down in living organism is to obtain energy. The complete break down of glucose normally occur via four different stages, which are glycolysis, oxidation of pyruvate, TCA cycle and electron transport chain. For each molecule of glucose that is metabolized, 38 molecules of ATP are always obtained. ATP is the only form of energy that is usable by cells to carry out life sustaining activities of the cells.

Answer:
<u>Animals and plants use oxygen for processing cellular respiration.</u>
Explanation:
Most of all organisms use oxygen to undergo cellular respiration with the help of the mitochondria that powers energy. Cellular respiration is needed to obtain energy for survival. As products of cellular respiration, ATP energy is created, and carbon dioxide + water is released from the organism. Thus, an ecosystem like a rainforest with animals and plants use oxygen for processing cellular respiration.
