Definition of cellular respiration
: any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products
- Cellular respiration is a series of reactions, occurring under aerobic conditions, during which large amounts of ATP are produced.
- —Teresa Audesirk and Gerald Audesirk
- One of the primary sources of energy is glucose, the basic building block of starch and many sugars in our diet. Its oxidation in cell respiration can be subdivided into three phases: glycolysis, the Krebs cycle and the system of electron transport.
