Multiple Choice
In the context of translation, what is the primary function of ribosomes in a cell?
A
They generate ATP through oxidative phosphorylation across an inner membrane.
B
They modify and sort proteins for secretion by adding carbohydrate groups.
C
They synthesize proteins by decoding mRNA and catalyzing peptide bond formation.
D
They replicate DNA by unwinding the double helix and copying nucleotides.
Verified step by step guidance1
Understand the process of translation in cell biology, which is the synthesis of proteins from messenger RNA (mRNA).
Recognize that ribosomes are the molecular machines responsible for reading the sequence of codons in mRNA.
Know that ribosomes facilitate the assembly of amino acids into a polypeptide chain by catalyzing the formation of peptide bonds between amino acids.
Differentiate ribosomes from other organelles by their specific role: they do not generate ATP, modify proteins by adding carbohydrates, or replicate DNA.
Conclude that the primary function of ribosomes is to synthesize proteins by decoding mRNA and catalyzing peptide bond formation.
