Document Summary

Chapter 18 oxidative phosphorylation": understand the overview (25-8). This chapter is about energetics in the mitochondrion, but mitochondria re symbiotic bacteria, and parallel processes are found everywhere in prokaryotic cells: oxidative phosphorylation the recycling of adp to atp for energy. Redox reactions allows flow of e- from nadh and fadh2 to o2 (reduced to water) Electron flow takes place in four large protein complexes embedded in mito membrane and make up etc. Overall rxn is exergonic: collectively, cac + etc + synthesis of atp cellular respiration, mitochondria is where oxy-phos takes place, bounded by double membranes. Outer; inner (highly folded ridges cristae (more sa): oxy-phos takes place in inner membrane which has two sides, membrane potential (cyto side + and matrix ) Intermembrane space: matrix site most cac and fatty acid oxy rxns. In prokaryotes, etc pumps and complexes found in cyto membrane (inner of 2: possibly created by endosymbiotic event (large cell engulfs small cell); have their own dna.
