a. Urea cycle removes two wastes from blood in liver, that is CO2 and ammonia
b. Urea cycle occurs exclusively in the cytosol
c. ATP is required for the reaction in which arginosuccinate is cleaved to form arginine
d. Urea is produced directly by the hydrolysis of ornithine
(1) a and c                (2) a and d
(3) a only                  (4) a, b, c and d

Dear student

Please refer the solution below for the said query


The correct option is (3).

The urea cycle helps in the removal of two wastes from blood in liver i.e CO2 and ammonia.

Urea cycle occurs in mitochondria and cytosol and is produced by hydrolysis of arginine. ATP is not required for the reaction in which arginosuccinate is cleaved to form arginine.

Hope this information clears your doubt about the topic.
