WebDec 5, 2024 · Breakdown of Pyruvate. In order for pyruvate, the product of glycolysis, to enter the next pathway, it must undergo several changes to become acetyl Coenzyme A (acetyl CoA). Acetyl CoA is a molecule that is further converted to oxaloacetate, which enters the citric acid cycle (Krebs cycle). The conversion of pyruvate to acetyl CoA is a … WebMar 14, 2024 · Figure: Breakdown of Pyruvate: Each pyruvate molecule loses a carboxylic group in the form of carbon dioxide. The remaining two carbons are then transferred to the enzyme CoA to produce Acetyl CoA. Step 1. A carboxyl group is removed from pyruvate, releasing a molecule of carbon dioxide into the surrounding medium. …
WebThe video claims that acetyl-coa from fatty acid oxidation cannot contribute to gluconeogenesis because the pyruvate dehydrogenase step is irreversible. Hypothetically acetyl coa could enter the TCA and become OAA. That OAA can be converted to phosphoenolpyruvate (PEP) by PEP carboxylase. The PEP can be converted to glucose …
