Question

The conversion of urea to ammonia depends on urease, an enzyme. how would the conversation be affected if the body could not make urease

Answer 1

The conversion of urea to ammonia depends on urease, an enzyme. If the body cannot make this conversion because of poor production of urease, this would lead to several complicated medical conditions like infection or urinary stones, peptic ulcer, and hepatic coma. 

Answer 2

   The answer here is quite different, an enzyme is always going to be specific, so for example, cows, they have inside their digestive system an enzyme to digest cellulose, if they didn't have this, it would cause several problems.

   In this case, if the conversion doesn't happen, the conversation wasn't going to happen too, and then the body would start to feel the symptoms, as well as your kidney, you'd put a lot of pressure on him to filter out all this urea that wasn't supposed to be there, and that could cause problems like urinary stones or infections that could lead you even to ulcers.
