Question

Mammalian carbamoyl phosphate synthetase I

A) is one of the most abundant enzymes in liver mitochondria.

B) is involved in the urea cycle.

C) catalyzes the synthesis of carbamoyl phosphate from bicarbonate and ammonia.

D) A and B only.

E) All of the above.

I think the answer is A, I dont think it catalyzes the synthesis of ammonia

A) is one of the most abundant enzymes in liver mitochondria.

B) is involved in the urea cycle.

C) catalyzes the synthesis of carbamoyl phosphate from bicarbonate and ammonia.

D) A and B only.

E) All of the above.

I think the answer is A, I dont think it catalyzes the synthesis of ammonia

a) is true, sicne it is in motchondria and is readily available

b) this is true, since urea requires of it (for the formation of carbamate )

c) this is also true, bicarbonate and ammonia are its primary raw materials

I would choose E, since all are true
