oxidative phosphorylation
the potential of nadh and fadh is converted to more atp through an electron transport chain with oxygen as the "terminal electron acceptor". most of the atp produced by aerobic cellular respiration is made by oxidative phosphorylation. this works by the energy released in the consumption of pyruvate being used to create a chemiosmotic potential by pumping protons across a membrane. this potential is then used to drive atp synthase and produce atp from adp and a phosphate group. biology textbooks often state that 38 atp molecules can be made per oxidised glucose molecule during cellular respiration (2 from glycolysis, 2 from the krebs cycle, and about 34 from the electron transport system). however, this maximum yield is never quite reached because of losses due to leaky membranes as well as the cost of moving pyruvate and adp into the mitochondrial matrix, and current estimates range around 29 to 30 atp per glucose.
cellular respiration
cellular respiration is a 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. the reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called "high-energy" bonds are replaced by stronger bonds in the products. respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. cellular respiration is considered an exothermic redox reaction which releases heat. the overall reaction occurs in a series of biochemical steps, most of which are redox reactions themselves. although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow release of energy from the series of reactions.
