What role does ATP play in the process of protein production within a cell?
A
It directly encodes the sequence of amino acids in a protein.
B
It serves as a structural component of ribosomes.
C
It provides the energy required for the formation of peptide bonds during translation.
D
It acts as a template for assembling amino acids into proteins.
Verified step by step guidance1
Understand the process of protein production within a cell, which involves transcription and translation. Translation is the stage where amino acids are assembled into a polypeptide chain to form proteins.
Recognize that ATP (adenosine triphosphate) is the primary energy currency of the cell, providing energy for various cellular processes, including translation.
During translation, peptide bonds are formed between amino acids to create a polypeptide chain. This process requires energy to drive the enzymatic activity of the ribosome and associated factors.
ATP provides the energy needed for the activation of amino acids and the formation of peptide bonds. Specifically, ATP is used during the charging of tRNA molecules with amino acids by aminoacyl-tRNA synthetases.
Clarify that ATP does not encode the sequence of amino acids, serve as a structural component of ribosomes, or act as a template for protein assembly. Its role is strictly to supply energy for the biochemical reactions involved in translation.
