WebJan 22, 2024 · Glycolysis, which translates to "splitting sugars", is the process of releasing energy within sugars. In glycolysis, a six-carbon sugar known as glucose is split into two molecules of a three-carbon sugar called pyruvate. This multistep process yields two ATP molecules containing free energy, two pyruvate molecules, two high energy, electron … WebAkt induces glycolysis through the phosphorylation and activation PFK2, which in turn activates PFK1. These enzymes convert Fructose-6-Phosphate into Fructose-1, 6-Bisphosphate, a key step in glucose metabolism. Akt may also be involved in activation of the nutrient-dependent Thr/Ser kinase, mTOR.
