Aerobic Respiration
This term describes the metabolic processes
that generate ATP in association with a chemiosmotic process driven
by a respiratory chain that depends on the use of oxygen as the ultimate
electron acceptor. Water is the ultimate reduced end product and in animal
cells these processes occur in mitochondria where ATP is made by oxidative
phosphorylation. In mitochondria tricarboxylic acid cycle activity and
fatty acid oxidation provide most of the reducing equivalents that fuel
this process but reducing equivalents released by metabolite oxidation
reactions in the cytosol can be shuttled into mitochondria to supply a
small proportion of ATP needs.
