Detailed explanation-1: -There are five major enzymes that are involved in the urea cycle: carbamoyl-phosphate synthetase 1, ornithine transcarbamylase, argininosuccinate synthetase, argininosuccinate lyase, and arginase.
Detailed explanation-2: -Excretion. The correct option is (C): Explanation of the correct option: Ornithine cycle occurs in the liver which is associated with the formation of urea for excretion.
Detailed explanation-3: -The biosynthesis of arginine can be divided into two pathways: the conversion of glutamate into ornithine and the synthesis of arginine from ornithine through the sequential action of the enzymes ornithine transcarbamylase (OTC), argininosuccinate synthetase (ASSY) and argininosuccinate lyase (ASL) [4, 5].
Detailed explanation-4: -4.1 The urea cycle: Overview The substrates are ammonia, bicarbonate, and aspartate (Fig. 2).
