Document Summary

In the electron transfer system, electron flow through protein complexes in the inner. Mitochondrial membrane: 3 major protein complexes included (serve as electron carriers) I, iii, and iv are integral membrane proteins located in inner mitochondrial membrane. H+ from mitochondrial matrix into intermembrane compartment: resulting h+ gradient between two areas supplies energy to drive atp synthesis by membrane-embedded atp synthase (enzyme) Instead of atp adp + p rxn powering ion transport against gradient, Ions move with gradient via proton-motive force, powering adp + P atp (reverse rxn: atp is formed at the headpiece while protons enter atp synthase via the basal unit, this flow of h+ powering atp synthesis = chemiosmosis. 32 atp molecules are produced for each molecule of glucose oxidized completely to. Co2 and h2o: nadh and fadh2 relationship to atp, every nadh releases a pair of electrons 2. 5 atp.
