- Review the following statements and discuss whether each one is correct, incorrect or partially correct: Con In the presence of oxygen glycolysis can yield a net production of 6 molecules of ATP per molecule of glucose. In the presence of oxygen glycolysis can yield a net production of 8 molecules of ATP per molecule of glucose. In the absence of oxygen glycolysis can yield a net production of 2 molecules of ATP per molecule of glucose. In the absence of oxygen glycolysis can yield a net production of 4 molecules of ATP per molecule of glucosearrow_forwardExplain how energy-investment and energy-harvestingsteps of glycolysis result in two net ATP.arrow_forwardGlycolysis is often split up into three phases: 1. Energy Investment 2. Sugar Splitting and 3. Energy Payoff. After splitting the 6-carbon sugar, Fructose 1,6-biphosphate, 4 ATP are generated by substrate-level phosphorylation. What is substrate-level phosphorylation? A. ATP generated by chemiosmosis B. ATP generated by the direct transfer of a phosphate from an organic molecule to ADP C. ATP generated by the fermentation of alcohol D. Transfer of phosphates between glucose molecules E. All of the abovearrow_forward

- Which of the following is an energy-requiring step of glycolysis? Electrons and hydrogen ions are transferred to NADH when a phosphate group is added to PGAL. A phosphate group is transferred from ATP to glucose to produce glucose-6-phosphate. Two phosphate groups are transferred from each intermediate to ADP, forming ATP.arrow_forwardIn each of two steps during the "Energy payoff stage" of glycolysis, ATP is generated when an enzyme uses one of the phosphate groups attached to one of the ends of a 3-carbon intermediate molecule to phosphorylate (add a phosphate group) ADP, forming ATP. This mechanism of producing ATP from ADP and a phosphate group is known as: Question 9 options: substrate level phosphorylation redox phosphorylation lactic acid fermentation oxidative phosphorylationarrow_forwardIn the conversion of G3P into pyruvate at the end of glycolysis, which of the following does NOT occur? electron carriers are reduced inorganic phosphate is added to the carbon structure substrate level phosphorylation resulting in ADP à ATP carbon is released as CO2arrow_forward
