Question

In glycolysis the name of the enzyme that converts dihydroxyacetone phosphate to glyceraldehyde-3-phosphate is triose phosphate isomerase aldolase fumarase aldoketase none of the above How does action of the enzyme dehydrogenase make its product less stable than its substrate? It moves similar charges closer to one another in the molecule. It creates a beta-keto acid. It restricts the freedom of its substrate by changing the geometry of one atom from tetrahedral to trigonal planar. It converts a ketone to an aldehyde. It actually result in a product nearly as stable as its substrate. Four of the steps in the citric acid cycle are oxidation/reduction reactions. How many of these use NAD^+ as a cofactor? 0 1 2 3 4

Explanation / Answer

55). Triode phosphate isomerase.

56). answer is (C)

57). Answer is (D) i.e. 3 NADH.
