BRAINCAKEThe Krebs Cycle.
The Krebs cycle also occurs in the matrix of the mitochondria. Acetyl coA reacts with 4-carbon oxaloacetate to form 6-carbon citrate and coA is released.
Citrate undergoes decarboxylation and dehydrogenation to form 5-carbon alpha ketogluarate (αKG). Carbon dioxide is released and NAD is reduced.
