There are eight chemical reactions that occur in the citric acid cycle process. The reactions of the citric acid cycle are shown in the figure below. acetyl-coenzyme A 0 CH₂-C-CoA HO-CH Reaction 7 O malate CH₂ CH || CH fumarate FADH₂ Reaction 6 FAD H+ + NADH NAD+ 1,0 H₂C CH₂ CH₂ Reaction 8 succinate ADP 0=C GTP CH₂ oxaloacetate Reaction 5 H-COA GDP ATP H₂O Reaction 1 C Reactions of the Citric Acid Cycle CH₂ CH₂ H-COA 0=C 1 CoA succinyl-CoA H+ HO-C Reaction CO₂ с CH₂ NADH CH₂ citrate Reaction 2 H-COA Reaction 3 CO₂ I CH₂ T CH₂ 0=C NAD+ HO–CH a-ketoglutarate CH, CH isocitrate NAD+ H+ + NADH In chapters 9 and 10, you were introduced to several classes of organic reactions. These classes include esterification, decarboxylation, hydration reactions, dehydration of alcohols, oxidation of alcohols, oxidation of aldehydes, reduction of aldehydes, and reduction of ketones. Find at least one of these reaction classes in the citric acid cycle. List the reaction number and the reaction. Write a…
Below 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…

Which of the following events does not occur during Krebs Cycle? Citrate synthase catalyzers the transfer of an acetyl group from acetyl coenzyme A to oxaloacetate to form citrate. Isocitrate dehydrogenase converts citrate to its isomer isocitrate. A carbon dioxide is released when alpha-ketoglutarate is oxidized to succinyl coenzyme A. The energy released from the conversion of succinyl coenzyme A to succinate is used to transfer a phosphate group to ADP to form ATP. During Krebs Cycle, succinate is oxidized to fumarate which is coupled to the reduction of FAD to FADH2. During electron transport, the electrons from FADH2 are transferred to coenzyme Q. Which of the following catalyzes these reactions? NADH dehydrogenase Succinate dehydrogenase FADH2 hydrogenase NADH hydrogenase reductase
