Which of the following urea cycle enzymes catalyzes the reaction hydrolyzing the release of urea from arginine? correct answer: Arginase Arginase releases urea from arginine through a hydrolytic cleavage. Which of the following enzymes is likely to be active in both the fed and fasted states? correct answer: Glutaminase Glutaminase in the liver is responsible for freeing ammonia from glutamine. In the fasted state, glutamine will be in excess due to protein catabolism while in the f...
