WebBasically, insulin promotes anything that will decrease blood glucose levels. This can happen in two ways: either converting glucose--> pyruvate (glycolysis) or by converting glucose-->glycogen (glucogenesis). Glucagon does the opposite, it promotes any pathway that will increase blood glucose levels. That is either by converting glycogen ... WebIn the liver, gluconeogenesis occurs. From an intuitive perspective, gluconeogenesis reverses both glycolysis and fermentation by converting lactate first into pyruvate, and … WebSep 15, 2024 · Based on those numbers, we can tell four things about gluconeogenesis: Your liver is where most of gluconeogenesis happens and lactate is its favorite substance. The kidney is the second most important gluconeogenesis source. Lactate is used 2.7 times more than the amino acid alanine and 3.2 times more than glutamine. meta learning algorithm

"WebJul 11, 2024 · 1. As far as I understand, you're correct. Gluconeogenesis and fatty acid oxidation go hand in hand. I think the simple way to understand it is that if glucose and fat are the two main sources of energy available to the liver, it wouldn't make sense to use glucose during gluconeogenesis so the liver uses beta-oxidation of FAs.
