what happen in stage 1, part 1 of glycolysis
glucose is phosphorylated using a phosphate from a molecule of ATP. This creates 1 molecule of glucose phosphate and 1 molecule of ADP.
what happen in stage 1, part 2 of glycolysis
ATP is then used to add another phosphate, forming ✨hexose biphosphate✨
what happen in stage 1, part 3 of glycolysis
Hexose bisphosphate is then split into 2 molecules of ✨triose phosphate.✨
what is stage 2 of glycosis
oxidation
what happen in stage 2, part 1 of glycolysis
Triose phosphate is oxidised (loses hydrogen), which then forms 2 molecules of pyruvate
what happen in stage 2, part 2 of glycolysis
NAD collects the hydrogen ions, forming 2 reduced NAD
what happen in stage 2, part 3 of glycolysis
4 ATP are produced, but 2 were used up in stage one, so there’s a net gain of 2 ATP
