Bacteria are single-celled microorganisms. The cell walls of these microorganisms serve as barriers to chemicals that might affect the processes that occur within a bacterial cell. Antibiotic are a type of substance used to stop bacterial growth. Some antibiotics cause the bacterial cell wall to rupture A) Antibiotics remove chloroplasts from plant cells to cause starvation.

B) Antibiotics interfere with the transport of intracellular and extracellular material

Sabrina Hinton · Answer 1

The correct answer is option B

The antibiotics usually interfere within the process of transpeptidation. In transpeptidation, residues of amino acids or peptide are transferred from one compound to another and this is very important for the strengthening of the cell wall of the bacteria. Antibiotics like penicillin inhibit the process of transpeptidation by attacking the serine residue and thus the strength of cell wall reduces and it burst out thereby killing the bacteria.
