Cellular respiration

Definition

Cellular respiration is a metabolic process that cells use to convert the energy stored in glucose into ATP (adenosine triphosphate), which powers cellular activities. It involves a series of reactions, including glycolysis, the Krebs cycle, and oxidative phosphorylation.
