Which one of the following also acts as a catalyst in a bacterial cell...
The correct answer is option D, 23 sr RNA.
Explanation:
Catalysts are substances that increase the rate of a chemical reaction by lowering the activation energy required for the reaction to occur. In bacterial cells, ribosomes are responsible for protein synthesis. Ribosomes are composed of two subunits, a large subunit, and a small subunit, both of which contain RNA molecules and proteins. Among the RNA molecules, there are three types of ribosomal RNA (rRNA): 5 sr RNA, 16 sr RNA, and 23 sr RNA.
While all three types of rRNA are involved in protein synthesis, 23 sr RNA acts as a catalyst by catalyzing the formation of peptide bonds between amino acids during the elongation phase of translation. It does this by bringing the aminoacyl-tRNA to the ribosome and positioning it in the correct site.
Therefore, option D, 23 sr RNA, also acts as a catalyst in a bacterial cell.
