A. Ammonia and glutamineB. Ammonia and asp artic acid
C. Glutamine and glutamic add
D. Glutamine and alanine
Ans.
B. Ammonia and Aspartic acid

cycle
• Takes place in liver and brain.
• 1st two reactions occur in mitochondria.
• 1st two reactions are rate controlling reactions.
• Nitrogen atoms arise from Ammonia and Aspartic acid
• Combination of “Hyperammonemia+ ‘t’Blood Glutaniine+4.Blood urea” suggests defect in Urea Cycle. Lethargy, vomiting, coma are associated.
