Question

Which one of the following statements about the urea cycle are correct? aUrea cycle removes two wastes from blood M liver,that is CO,and ammonia bUrea cycle occurs exclusively in the cytoso CATP is required for the reaction in whic arginosuccinate is cleaved to form arginine dUrea is produced directly by the hydrolysis !? ornithine (1)a and c (2)a and d (3)a only (4)a,b,c and d

Answer 1

Answer: -

option 3 is correct

Explanation : -

• In urea cycle formation of carbamoyl phosphate occur by the combination of ammonia , CO2 and ATP thus it remove wastes from blood
• urea cycle occurs in liver that includes Mitochondria and cytosol
• when Argininosuccinate is cleaved to form Arginine no ATP is required instead of it Argininosuccinate lyase enzyme is required
• urea is produced by the hydrolysis of Arginine
