The ornithine cycle a level biology
WebbL -Ornithine is one of the products of the action of the enzyme arginase on L - arginine, creating urea. Therefore, ornithine is a central part of the urea cycle, which allows for the disposal of excess nitrogen. Ornithine is recycled and, in a manner, is a catalyst. First, ammonia is converted into carbamoyl phosphate ( H. 3 ).
