This Concept Map, created with IHMC CmapTools, has information related to: 03. Electron Transport Chain, Enz: Complex II (Succenate Dehydrogenase) to FADH, More negative E implies higher propensity to give up e- note NADH has a more neg E than FADH2, FADH can also come from Fatty acyl-CoA Dehydrogenase, Complex I (NADH Dehydrogenase) Functions Transfer 2e- + 2H+, Complex III functions Pumps 4H+, FAD pathway entails Pumping 6 H+, H+ both carried to Complex I (NADH Dehydrogenase), FMNH2 a CoEnzyme, Pumping 6 H+ which can be used to drive 1.5 ATP (6/4), Subunit 1 specificially, first to Heme-a, FMNH2 next transfered to Ubiquinone (CoQ), Ride along out surface of inner mito membrane carries e- to Complex IV (Cytochrome c-oxidase), Transfer electrons to Cytrochrome C, Complex IV (Cytochrome c-oxidase) functions Passes e- to O2, Fe+3 to Fe+2 implies 1 e- at a time, More positive reduction potentials E thus Thermodynamically favorable, ELECTRON TRANSPORT CHAIN lives on Inner mitochondrial membrane, Subunit 2 (Cu-A site) unit can Transfer 1 e- at a time, Complex IV (Cytochrome c-oxidase) inhibited by Cyanide, 2 molecules of H20 notes Incomplete reduction leads to H202 & OH- both are bad
