Coo COO™ I HIC-H H-C-H COO™ succinate isomerase hydrolase O ligase transferase oxidoreductase succinate dehydrogenase FAD FADH2 H-C || C-H COO fumarateBelow is an image of the Krebs cycle: acetyl-CoA oxaloacetate COASH H20 NADH NAD* H20 malate citrate fumarate isocitrate FADH2 NAD* CO2 FAD АТР NADH + ADP succinate GTP NAD+ a-ketoglutarate H20 GDP NADH + CO2 COASH succinyl CoA COASH Consider the conversion of succinate to fumarate, which is coupled with the production the electron carrier FADH2. 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…Lactate can be converted into pyruvate by the enzyme lactate dehydrogenase and the coenzyme NAD+. Write the reaction in the standard biochemical format, using a curved arrow to show the involvement of NAD+.
