During translation,the reaction catalyzed by peptidyl transferase is coupled to which of the following? A)ATP → ADP + P_i B)ATP → AMP + PP_i C)GTP → GDP + P_i D)GTP → GMP + PP_i E)Release of the tRNA in the P site

Question

Quizplus · Accepted Answer

The reaction catalyzed by peptidyl transferase is the formation of a peptide bond between the amino acid on the tRNA in the A site and the growing polypeptide chain on the tRNA in the P site. This reaction is coupled to the release of the tRNA in the P site, as the ribosome moves down the mRNA to the next codon. The other options (A, B, C, D) involve the hydrolysis of nucleotides and are not directly involved in the peptidyl transferase reaction.
