Question

How many atp and gtp molecules are required for incorporation of 25 amino acids in peptide chain?

Answer 1

One ATP is hydrolyzed to AMP during amino acid activation. Thus, the formation of each peptide bond uses 3 high-energy molecules, one ATP and two GTP. So, the correct answer is option D.

Answer 2

Answer:

One molecule of GTP is required for initiation, and 398 molecules of GTP are needed to form 199 peptide bonds........................
