Protein Synthesis And Urea Cycle

Question 1

What is the principal ammonia scavenger and transporter in muscles?

Answer 1

Alanine

Question 2

What happens to amino acids surplus to requirement for protein synthesis?

Answer 2

They can be metabolized to non-nitrogenous substances
E.g. glucose, glycogen or fatty acids

Or they can be oxidised to generate ATP

Question 3

What is transamination?

Answer 3

Chemical reaction that transfers an amino group to a ketoacid to form new amino acids
