Question

The enzyme urease catalyzes this reaction. If urease is added to a solution that contains ammonia and other nitrogen-containing compounds (but no urea), will the urease catalyze any reactions? E

Answer 1

The enzyme urease catalyze the hydrolysis of urea into ammonia and carbon dioxide. If urease is added to any compound which has no urea, it will not catalyze any reaction because if there is no urea, urease will not bind to any substance.

Answer 2

Urease is an enzyme.

Enzymes are highly specific in the reactions they catalyze.

Enzymes can typically bind only to the substrate(s) for the reaction they catalyze.

If the solution contains no urea, urease will not bind to any of the substances in the solution, so it will not catalyze any reactions in the solution.
