Cellular respiration

Definition

Cellular respiration is the process of oxidizing biological fuels using an inorganic electron acceptor, such as oxygen, to drive production of adenosine triphosphate (ATP), which stores chemical energy in a biologically accessible form. Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells to transfer chemical energy from nutrients to ATP, with the flow of electrons to an electron acceptor, and then release waste products.
