The enzyme urease catalyzes the breakdown of urea in the body. urease breaks urea down to 2nh3+co2. this is an example of a hydrolysis reaction (urea plus water). for each equivalent of carbon dioxide (co2), two equivalents of ammonia (nh3) are produced. label the enzyme, substrate, enzyme–substrate complex, enzyme–product complex, and product in the enzymatic reaction for the breakdown of urea by urease using the induced-fit model
