Question

Peptidyl transferase is an enzyme that functions to enable the creation of a polypeptide chain during the process of translation.

How does peptidyl transferase perform this function?

Answer
A
Peptidyl transferase decreases the amount of energy needed to create a peptide bond between amino acids.

B
Peptidyl transferase speeds up translation by allowing more codons into the ribosome.

C
Peptidyl transferase increases the length of the polypeptide chain by transferring energy to the amino acids.

D
Peptidyl transferase creates the mRNA from the information in the template strand of DNA.

Answer 1

Answer: D

Explanation: the image shows this. Let me know if I’m right.

Answer 2

Peptidyl transferase decreases the amount of energy needed to create a peptide bond between amino acids. (Option A).

What is peptidyl transferase?

Peptidyl transferase performs its function by catalyzing the formation of peptide bonds between amino acids during the protein synthesis process known as translation.

It facilitates the bond between the amino group of the amino acid attached to the A-site tRNA and the carboxyl group of the amino acid attached to the P-site tRNA, which is already part of the growing polypeptide chain.

Thus, the correct answer to how peptidyl transferase performs its function is Option A: Peptidyl transferase decreases the amount of energy needed to create a peptide bond between amino acids.
