1. Acetyl-Co, 2C combines with oxaloacetate, 4C to form citrate, 6C
2. Decarboxylation to remove carboxyl group from 6C citrate to release 1 molecule of CO2
3. Dehydrogenation, transferring protons and electrons to oxidised NAD, NAD+, to form reduced NAD, NADH + H+
4. Substrate-level phosphorylation occurs, where 1 ATP is produced
5. Dehydrogenation occurs, transferring protons and electrons to oxidised FAD, FAD, to form reduced FAD, FADH2
6. Dehydrogenation occurs, transferring protons and electrons to oxidised NAD, NAD+, to form reduced NAD, NADH + H+
7. Oxoacetate regenerated
