Does the process of glycolysis require an input of energy? provide specific evidence from model 1 to support your answer.

Yes. In the beginning, glycolysis requires 2 ATP molecules. One ATP allows for the phosphorylation of the glucose molecule to fructose-6-phosphate and another phosphorylation to fructose-1, 6-biphosphate. The fructose-1, 6 - bisphosphate is then cleaved into two glyceraldehyde-3-phosphates that then enter the energy generating part of the glycolysis biochemical reaction.
