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…
- Help me pleaseMost fatty acids have an even number of carbons and, therefore, are completely metabolized to acetyl-CoA. A fatty acid with an odd number of carbonsis metabolized to acetyl-CoA and one equivalent of propionyl-CoA. The following two reactions convert propionyl-CoA into succinyl-CoA, a citric acidcycle intermediate, so it can be further metabolized. Each of the reactions requires a coenzyme. Identify the coenzyme for each step. From what vitaminsare the coenzymes derived? (Hint: see Chapter 23.) COO− COO−CH2CH2methylmalonyl-CoA succinyl-CoA CH3CH2 SCoAIdentify the label in the correct position in the following: C-1 of acetyl CoA to malate (one cycle) 3-14C OAA + unlabeled acetyl-CoA to succinate.
