BIOL 130 Lecture Notes - Lecture 17: Atp Synthase, Intermembrane Space, Cell Membrane
Document Summary
The etc generates a proton gradient: this gradient drives atp synthase, runs like a reverse ion pump, moves down chain complexes can act as proton pumps. It uses proton gradient to drive the catalytic drive to make atp. Energy comes from redox: h+ gradient generates a proton gradient, the only way protons can come back into the cell (atp synthase, atp synthase has 4 components. Has channel where protons flow through it to get to rotor. When the rotor spins all the way around, the protons get released into the matric. Energy is going to cause change in catalytic unit at bottom. Takes kinetic energy from rob and turns adp to atp. In bacteria, it is located on plasma membrane. Chemiosmosis energy stores in ion gradient driving cellular work: uses energy of ion gradient to do work, uses proton gradient to make atp.
