If this reaction was NOT coupled with the production of FADH2 (and only catalyzed the conversion of succinate to fumarate), how would this impact ATP production through cell respiration? OATP production would stop because no high energy electron carriers would be produced ATP production would still occur, but there would be a much lower ATP yield because a large number of electron carriers are no longer being made ATP production would stop because without FADH2 we will no longer have electrons moving through the electron transport chain ATP production would still occur, but there would be a slightly lower ATP yield because a small number of…Acetyi CoA Oxaloncetate CoA NADH NAD: Citrate Isccitrate Malate NAD co NADH Funaate »FADH; FAD a- Ketoglutarate Succinate NAD ATP Succinyt CuA NADH ADP - P, If you were told to add one of the eight citric acid cycle intermediates to the culture medium fo yeast growing in the laboratory, what do you think would happen to the rates of ATP and carbon dioxide production?
