Running Head: ACE BIOLOGY MODULE 3:41Glycolysis and Fermentation Assignment1. Is oxygen required for glycolysis?Oxygen is not required.2. Define glycolysis.A series of endothermic and exothermic reactions that convert glucose into pyruvate withthe use of two molecules of ATP.3. Why is ATP needed to initiate glycolysis?ATP provides the energy for initiating glycolysis.4. Describe the first reaction in glycolysis. Is this reaction catalyzed by an enzyme? (2 points)One molecule of ATP donates its terminal phosphate to the glucose molecule. Thisreaction is catalyzed by an enzyme.5. Define phosphorylation.The addition of a phosphate group to a molecule.6. Describe the second reaction of glycolysis.Another molecule of ATP donates its terminal phosphate group to the other end of thesix-carbon chain.7. The transfer of phosphate groups to glucose and fructose is not a100% transfer of energy.Some energy is lost. In what form is this lost energy?
