WebMar 6, 2024 · It is worth noting that animals are unable to use fatty acids as materials for gluconeogenesis in net amounts, but they can, in fact, use glycerol in both glycolysis and gluconeogenesis. ... As noted, pyruvate produced in glycolysis can be oxidized to acetyl-CoA, which is itself oxidized in the citric acid cycle to carbon dioxide. That is not ... WebThese enzymes are typically regulated by similar molecules, but with opposite results. For example, acetyl CoA and citrate activate gluconeogenesis enzymes (pyruvate …
WebAnd, for fatty acids, the main precursor for fatty acid synthesis is the molecule acetyl-CoA. And, as a relevant side note, I wanna point out that acetyl-CoA happens to be in equilibrium with another molecule in the cell called acetoacetyl-CoA. And oxaloacetate if you remember is in equilibrium with a lot of the intermediates of the Krebs cycle. WebMar 6, 2024 · Acetyl CoA, of course, can be used for ATP synthesis via the citric acid cycle.
