Forms when coenzyme a attaches to two carbons
WebThe first event is the decarboxylation (removal of a carboxyl (-COO -) group) to form carbon dioxide (red). The intermediate compound then donates two electrons (green) to NAD + to reduce it to NAD - (not shown). Then an hydrogen ion is donated by coenzyme A complete the formation of NADH.

WebApr 9, 2024 · The 3-carbon pyruvate is converted into a 2-carbon acetyl group with a carboxyl being removed as CO 2. The acetyl group is attached to coenzyme A to form acetyl coenzyme A (acetyl-CoA), a key precursor metabolite. As the two acetyl groups become oxidized to acetyl-CoA, two molecules of NAD + are reduced to 2NADH + 2H +. http://pressbooks-dev.oer.hawaii.edu/biology/chapter/oxidation-of-pyruvate-and-the-citric-acid-cycle/
