Unformatted text preview: Lecture Connections 19 | Oxidative Phosphorylation and Photophosphorylation 2009 W. H. Freeman and Company Proton-motive Force electrochemical proton gradient created by: actively transported protons across the membrane passing electrons to coenzyme Q that picks up protons from the matrix electrons and protons from QH 2 are released to the inter-membrane side Chemiosmotic Model for ATP Synthesis Electron transport sets up a proton-motive force Energy of proton-motive force drives synthesis of ATP Free Energy in NADH Question Calculate the amount of energy conserved in the proton gradient across the inner mitochondrial membrane per pair of electrons transferred through the respiratory chain from NADH to oxygen. Assume = 0.15 V and the pH difference is 0.75 units Driving force for ATP synthesis Difference in proton concentration Difference in Charge Experiment Isolate mitochondria Give ADP, Pi, succinate What do you expect to see? ATP Synthesis is Coupled to...
