WebIn the Krebs cycle, decarboxylation occurs in two steps. First oxidative decarboxylation occurs during the conversion of isocitrate into α-ketoglutarate. This reaction is catalyzed by isocitrate dehydrogenase. Second oxidative decarboxylation takes place when α-ketoglutarate is converted to succinyl-coenzyme A with the help of α ... Web13 aug. 2024 · Figure 15.2. 1: After glycolysis, two 3-carbon pyruvates enter the mitochondria, where they are converted to two 2-carbon acetyl-CoenzymeA (CoA) molecules. Acetyl-CoA then enters the Krebs Cycle. Note that the carbons removed become carbon dioxide, accounting for two of the six such end products of glucose …
