Chemiosmosis
*Energy released from
another rxn
*Glucose hydrolysis
*SLR
*H atom released
H —> e & H*
H* power Atp-synthase &
rotates
*ADP+Pi = ATP

acetyl CoA
1. Acetyl group + oxaloacetate
2-3. Decarboxylyation &
oxidation
4. SLR
5-6. Oxidation
1.NADH is oxidised & -> H
2. H -> H* + e
3. E move along ETC &
power it
4. ETC pump H* in intermem
5. H* gradient
6. Chemiosmosis so ATP
produced
7. O2 is final acceptor of e
& bind to H* + e -> H2O
