The synthesis of one peptide bond involves hydrolysis of: (A) 1 ATP & 3 GTP, (B) 2 ATP & 2 GTP, (C) 3 ATP & 1 GTP, (D) 4 ATP
Answer is B. During the translation process, the formation of one peptide bond (adding one amino acid) consumes 4 high energy phosphates (2 from ATP & 2 from GTP). Eukaryotes will add 6 amino acids and prokaryotes will add 18 amino acids per second. (Refer: Harper's Illustrated Biochemistry, 26th edition, pg no: 370)
