Question

How does respiration help in the release of energy?

Answer 1

Role of respiration in the release of energy:

1. Respiration is a metabolic process in which an organism's living cells use oxygen to obtain energy (in the form of ATP) and release carbon dioxide as a byproduct of the oxidation of complex organic molecules.
2. Using oxygen, glucose is completely oxidized to carbon dioxide and water during cellular respiration.
3. ATP molecules store the energy released during respiration.
4. The aerobic respiration process generates 36 to 38 ATP molecules by breaking down one glucose molecule via glycolysis, Krebs cycle, and oxidative phosphorylation via electron transport chain.
