Document Summary
Pump" implying they"re going against a concentration gradient: protons come back in through atp synthase. Atp and why do we need to keep making it: amount of atp needed per day, sedentary males (approximately 70 kilograms) need approximately 8 400 kj per day. Overview of oxidative phosphorylation: oxidative phosphorylation is a process in which atp is formed as a result of the transfer of electrons from, nadh and fadh2 to oxygen. Location: inner mitochondrial membrane: leads to pumping of protons out of the mitochondrial matrix: Unequal distribution of protons: creates a ph gradient, creates a transmembrane electrical potential, creates proton-motive force. Flow of protons back into mitochondrial matrix: releases free energy, this energy is captured and used to phosphorylate adp to, movement of electrons to oxygen, occurs through protein complexes: produce atp. Electron carriers are complexed to protein: protein complexes are integral proteins: Located in inner mitochondrial membrane: within each mitochondrion:
