Final answer:
Cellular respiration converts carbohydrates and oxygen into carbon dioxide and water while generating ATP, the energy currency of cells.
Step-by-step explanation:
Cellular respiration is a set of chemical reactions that convert carbohydrates and oxygen into carbon dioxide and water.
The main purpose of cellular respiration is to generate energy in the form of ATP (adenosine triphosphate), which is used by cells to perform work.
During cellular respiration, glucose and oxygen are broken down, releasing energy and producing carbon dioxide and water as byproducts.
