Cellular respiration

Cellular respiration is the set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. It includes several core steps:


 * 1) Glycolysis
 * 2) Oxidative decarboxylation of pyruvate
 * 3) Citric acid cycle (Krebs cycle)
 * 4) Oxidative phosphorylation
