E)It requires no outside source of additional energy,such as ATP.

Question

Quizplus · Accepted Answer

Peptidyl transferase is an enzymatic activity of the ribosome, specifically associated with the large subunit, that catalyzes the formation of peptide bonds between amino acids during protein synthesis. It functions as a ribozyme, meaning its catalytic activity is not protein-based but rather RNA-based. It does not require ATP or any external energy source to catalyze peptide bond formation. However, peptidyl transferase itself does not move the ribosome along the mRNA; this movement is facilitated by other factors involved in translation.
