The synthesis of one peptide bond involves hydrolysis of 
Select and explain. 
A. 1 ATP & 3 GTP, B. 2 ATP & 2 GTP, C. 3 ATP & 1 GTP, D. 4 ATP
B: 2 ATP & 2 GTP
Answer: B: 2 ATP & 2 GTP 
Explanation: 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)
