What enzyme catalyzes the reaction shown above a) ß-galactosidase b) hexokinase c) glucose dehydrogenase d) cycloreductase 27. The step that commits the cell to metabolize glucose is catalyzed by(2 p) a. hexokinase. Solution for The enzyme urease catalyzes the reaction of urea, 1NH2CONH22, with water to produce carbon dioxide and ammonia. An enzyme's name is often derived from its substrate or the chemical reaction it catalyzes, with the word ending in -ase. In enzyme kinetics, the reaction rate is measured and the effects of varying the conditions of the reaction are investigated. Examples of Enzyme-Catalyzed Reactions.
