Vedclass · Answer

(C) The urea cycle,also known as the Krebs-Henseleit cycle $(1932)$,is a series of biochemical reactions that occur in the liver to convert toxic ammonia into urea.$1$. The cycle involves the formation and transformation of three key amino acids: ornithine,citrulline,and arginine.$2$. Ornithine combines with carbamoyl phosphate to form citrulline.$3$. Citrulline then reacts with aspartate to form argininosuccinate,which is subsequently converted into arginine.$4$. Finally,arginine is hydrolyzed to release urea and regenerate ornithine,allowing the cycle to continue.Therefore,the correct option containing the primary amino acids involved in the cycle is ornithine,citrulline,and arginine.

$a$. Bony fish	$1$. Crustaceans
$b$. Terrestrial amphibian	$2$. Ammonotelic
$c$. Land snails	$3$. Ureotelic
$d$. Prawn	$4$. Uricotelic
