Several different classes of enzymes are needed for the catabolism of carbohydrates. Which of the following descriptions best matches the function of a dehydrogenase?

A. An enzyme that catalyzes the addition of phosphate groups to other molecules

B. An enzyme that catalyzes the rearrangement of bonds within a single molecule

C. An enzyme that catalyzes a change in the position of a specific chemical group within a single molecule

D. An enzyme that catalyzes the oxidation of a molecule by removing a hydride ion

Solutions

Expert Solution

Its answer will be (d) an enzyme that catalyaes the oxidation of molecule by removing a hydride ion.

It oxidises the substrate by reducing an electron pair usually NAD+/NADH+ or FAD/FADH

List and explain the role of the enzymes needed for the following routing of nitrogen into the urea cycle: Start with a molecule of aspartate in peripheral tissue (e.g., muscle) and end with the nitrogen derived from that original aspartate molecule released as free ammonia in the liver. (Hint: routing should be by the major non-toxic carrier of nitrogen in the blood).
