Cellular Respiration

The metabolic process by which cells convert nutrients into energy (ATP), involving the oxidation of food molecules and the release of waste products.

Citric Acid Cycle

The Citric Acid Cycle, also known as the Krebs cycle, is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins.

Cellular Respiration

Cellular respiration is a biochemical process in cells where organic molecules are broken down to release energy for use by the cell.
