What is the end product of the process of respiration? * A. glucose and oxygen
B. water and carbon dioxide

B. carbon dioxide and water

Explanation:

Respiration is a process that animals and plants undergo to create energy to grow, move and sustain life.

The equation for cellular respiration is:

glucose + oxygen —> ATP + carbon dioxide + water

The organisms use glucose from food and oxygen to create ATP (useable energy), carbon dioxide and water.

Therefore, the answer is B. Carbon dioxide and water. Glucose and oxygen are not the end results, they are used to make the end results.
