1. Which of the following compounds in the citric acid cycle have high-energy bonds or transfer chemical energy?
NADH, NAD+, GTP, Q, CO2, CoA, QH2
2. The reactions of the citric acid cycle are labled as: 1. citrate synthase 3. isocratic dehydrogenase 4. alpha-ketoglutarate dehydrogenase
Which of the following molecules inhibit reaction 1? Which of the following molecules or ions activate reaction 3? Which of the following molecules inhibit reaction 4?
3. The citric acid cycle has a catabolic role, oxidizing acetate into CO2 and generating energy, and an anabolic role. Many of the citric acid cycle intermediates serve as precursors for the biosynthesis of larger molecules. Move each of the following molecules to the precursor that gives rise to it.
citrate to? alpaha-ketoglutarate to? succinyl-CoA to? malate to? oxaloacetate to?
options are: glucose, heme, glutamate, cholesterol, and pyruvate.
