Question

If the ribosomes of a cell are destroyed

• A. Respiration will cease soon
• B. Protein synthesis will stop
• C. Lipid synthesis will stop
• D. All of the above

Answer 1

Answer: (B)

Protein synthesis will stop

Ribosomes are naked ribonucleoprotein particles found in both prokaryotic and eukaryotic cell. They carry out the process of protein synthesis. Each ribosome particle is made up of two subunits-small and large subunit. Smaller subunit has point for recognition of mRNA while the larger subunit has peptidyl transferase activity, binding site for tRNA and the A site. The P site is jointly formed by the two subunits. During protein synthesis the incoming or next amino acid to be attached to the growing chain is held at the A site and the growing peptide chain is held at P-site. The peptidyl transferase activity catalyzes the peptide bond formation between the amino acids.

So, the correct answer is 'Protein synthesis will stop'.
