Question: In heart cells deprived of oxygen during a myocardial infarction

A. the mitochondrial proton pump slows down, preventing ATP synthesis by oxidative phosphorylation

B. the citric acid cycle will accelerate to provide more electrons for ATP synthesis

C. the electron transport chain will accelerate to provide more protons for ATP synthesis

D. anaerobic glycolysis will decrease, and the conversion of glucose to CO2 will increase

E. product inhibition by NADH and ADP will slow many of the reactions in the citric acid cycle

Explanation / Answer

Due to the lack of the oxygen or the state of oxygen deprivation there is interruption in the overall metabolism of the mitochondria. Due to the inability of the mitochondria to work at faster pace and pump proton, it lead to prevention of the ATP synthesis that is required for performing the energy oriented work.
