Cellular respiration is a set of metabolic processes occurring inside cells that convert biochemical energy from food into a chemical compound called adenosine triphosphate (ATP), thereby releasing energy and waste products.
Glucose is converted into ATP by cellular respiration.
One molecule of glucose produces 38 ATP molecules by aerobic respiration in the cytoplasm and mitochondria.
The steps involved in cellular respiration are glycolysis, Krebs cycle, and oxidative phosphorylation.
