Glycolysis is a metabolic pathway by which organisms extract energy from glucose. It is the first step of cellular respiration. Glycolysis has two phases: in the first phase, energy is invested into making glucose unstable and split apart into three-carbon molecules, one of which is glyceraldehyde-3-phosphate (the other is an unstable isomer). In the second phase, glyceraldehyde-3-phosphate is gradually converted into pyruvate, generating NADH and ATP. #sciencetok #fypシ #womeninstem #apbio #apbiology #premed #biologymemes #biologyclass #CapCut
