Question

During strenuous exercise, anaerobic conditions can result if the cardiovascular system cannot supply oxygen fast enough to meet the demands of muscle cells. Assume that a muscle cell s demand for ATP under anaerobic conditions remains the same as it was under aerobic conditions. What would happen to the cell s rate of glucose utilization? Glucose utilization would increase a lot. Glucose utilization would remain the same. Glucose utilization would decrease a little. Glucose utilization would increase a little. Glucose utilization would decrease a lot. Under anaerobic conditions (a Lack of oxygen), glycolysis continues in most cells despite the fact that oxidative phosphorylation stops, and its production of NAD (which is needed as an input to glycolysis) also stops. The diagram Illustrates the process of fermentation, which is used by many cells in the absence of oxygen. In fermentation, the NADH produced by glycolysis is used to reduce the pyruvate produced by glycolysis to either lactate or ethanol. Fermentation results in a net production of 2 ATP per glucose molecule.

Explanation / Answer

Glucose utilization would increase a lot to meet the requirement of energy.
