Biotin Figure 2. Acetyl-CoA Carboxylase 1 and Acetyl-CoA Carboxylase 2. In the cytosol of liver cells, fatty acids are converted to acyl-CoA, and glucose undergoes glycolysis that produces pyruvate. Acyl-CoA is shuttled into the mitochondria via CPT1-mediated transport and undergoes β-oxidation that generates acetyl-CoA. In addition, pyruvate is converted to acetyl-CoA in the mitochondria, and acetyl-CoA is condensed with oxaloacetate to form citrate. The latter can be exported to the…

Oxidative Decarboxylation of pyruvate: in mitochondria; pyruvate formed during glycolysis is transported from cytoplasm into mitochondrial matrix where it is decarboxylated (loses a CO2) & the acetyl group that remains is transferred to coenzyme A to form acetyl CoA; in the process, NAD+ is reduced to NADH

The Krebs Cycle is the central metabolic pathway in all aerobic organisms. The cycle is a series of eight reactions that occur in the mitochondrion.  These reactions take a two carbon molecule (acetate) and completely oxidize it to carbon dioxide. The cycle is summarized in the following chemical equation:  acetyl CoA + 3 NAD + FAD + ADP + HPO4-2 ---------------> 2 CO2 + CoA + 3 NADH+ + FADH+ + ATP

The fate of carbons in the TCA cycle. Acetyl-CoA is the substrate for the TCA cycle and it is converted to 2 moles of CO2. To do this, it is attached to OAA which is a carrier; the TCA cycle intermediates are not true intermediates. The fine point is that whereas the net reaction is the oxidation of acetyl-CoA, microscopically, it is the carbons from the carrier that get oxidized.
