In the last reaction of the citric acid cycle, malate is dehydrogenated to regenerate the oxaloacetate necessary for the entry of acetyl-CoA into the cycle: L-Malate + NAD+ → oxaloacetate + NADH + H* AG'° = 30.0 kJ/mol (a) Calculate the equilibrium constant for this reaction at 25 °C. (b) Because AG°' assumes a standard pH of 7, the equilibrium constant calculated in (a) corresponds to [oxaloacetate][NADH] Keq [L-malate][NAD*] The measured concentration of L-malate in rat liver mitochondria is about 0.20 mM when [NAD*]/[NADH] is 10. Calculate the concentration of oxaloacetate at pH 7 in these mitochondria. (c) To appreciate the magnitude of the mitochondrial oxaloacetate concentration, calculate the number of oxaloacetate molecules in a single rat liver mitochondrion.

X shows a fairly sharp decrease in its activity when the pH goes much lower than 5.8. One likely interpretation of this pH activity is that: a Glu residue on the enzyme is involved in the reaction. O the enzyme uses NADH has a cofactor the enzyme uses coenzyme A has a cofactor O a Tyr residue on the enzyme is involved in the reaction. O a His residue on the enzyme is involved in the reactionAnswer the ff. questions: 1. To which class does each enzyme belong? Explain your answers. a.) pyruvate decarboxylase b.) alanine aminotransferase c.) alcohol dehydrogenase d.) hexokinase 2. Substrates and reactive groups in an enzyme’s active site must be precisely aligned in order for a productive reaction to occur. Why, then, is some conformational flexibility also a requirement for catalysis? 3. Some plants contain compounds that inhibit serine proteases. It has been hypothesized that these compounds protect the plant from proteolytic enzymes of insects and microorganisms that would damage the plant. Tofu, or bean curd, possesses these compounds. Manufacturers of tofu treat it to eliminate serine protease inhibitors. Why is this treatment necessary?
