where does the krebs cycle occur
1 To do so, pyruvate molecules are processed through the Krebs Cycle, also known as the citric acid cycle. 2  This cycle occurs in the mitochondria. 3  KREBS CYCLE YIELDS (2 CYCLES, 1 FOR EACH PYRUVATE): 24 ATP; 6 NADH + H + , 2 GTP, 2FADH Click HERE for an excellent animation of the Krebs Cycle.itrate is formed when the acetyl group from acetyl CoA combines with oxaloacetate from the previous Krebs cycle. 3. Citrate is converted into its isomer isocitrate. 4. Isocitrate is oxidized to form the 5-carbon Î±-ketoglutarate. This step releases one molecule of CO 2 and reduces NAD + to NADH 2 + .
