| Front | krebs cycle |

| Back | - occurs in matrix and each cycle results in breakdown of an acetyl group, involves decarboxylation, dehydrogenation and substrate level phosphorylation - H2 atoms released accepted by NAD and FAD to from reduced NAD/FAD, of which will help form ATP later on, CO2 formed is a by-product and ATP formed is used in energy using reactions - acetyl CoA transfers acetyl group (2 carbons) to KC, where it combines with oxaloacetate (4 carbons) to form citrate (6 carbons), which ndergoes decarboxylation and dehydrogenation to form a reduced NAD and CO2 and a 5 carbon compound, the 5 carbon compound also undergoes decarboxylation and dehydrogenation to form another reduced NAD and CO2, aswell as reforming oxaloacetate - cycle continues, forming more CO2, 2 more reduced NAD molecules and 1 more reduced FAD molecule, ATP formed aswell by substrate level phosphorylation |
