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…Which of the following statements is true about the chymotrypsin reaction? 1. The catalytic triad at the active site is formed by three residues: His, Gly, and Ser 2. When the substrate is p-Nitrophenylacetate, the rate-limiting step is the release of p-Nitrophenolate. 3.
