Question: how many molecules of atp are used during glycolysis?
Answer: In glycolysis, glucose is broken down ultimately into pyruvate and energy, a total of 2 ATP, is derived in the process (Glucose + 2 NAD+ + 2 ADP + 2 Pi --> 2 Pyruvate + 2 NADH + 2 H+ + 2 ATP + 2 H2O). The hydroxyl groups allow for phosphorylation. The specific form of glucose used in glycolysis is glucose 6-phosphate.
