WebJul 20, 2024 · The main difference between glycolysis and gluconeogenesis is in their basic function: one depletes existing glucose, while other replenishes it from both organic (carbon-containing) and inorganic (carbon-free) molecules. This makes glycolysis a catabolic process of metabolism, while gluconeogenesis is anabolic.
