The Citric Acid Cycle Problems Problem : What is the name of the enzyme that catalyzes the reaction that joins a molecule of acetyl-CoA and oxaloacetate? Solution for Problem 1 >> Citrate synthase. Problem : From which position on citrate to which position is the –OH group transferred in the second step of the citric acid cycle by the enzyme acontinase? Solution for Problem 2 >> Citrate has an –OH group on its 3' carbon. The enzyme acontinase moves the –OH to the 4' position. Problem : What two types of reactions are catalyzed by the enzyme isocitrate dehydrogenase in the third reaction of the citric acid cycle? Solution for Problem 3 >> The first reaction is an oxidation and the second is a loss of carbon dioxide, or a decarboxylation. Problem : In which of the first five steps of the citric acid cycle is NADH produced? Solution for Problem 4 >> NADH is produced in the third and fourth reactions of the citric acid cycle by the enzymes isocitrate dehydrogenase and alpha-ketoglutarate dehydrogenase.
