Which antibiotic act on the cell wall of bacteria?
1 $\beta$-lactum group
2 Tetracycline
3 Neomycin
4 Streptomycin
Explanation:
$\beta$-Lactum antibiotics are distinguished by a lactum ring in their molecular structure. This ring inhibits the synthesis of the peptidoglycan layer of bacterial cell wall.

Broad spectrum antibiotic
1 acts on all bacteria and virus
2 is effective in very small amount
3 acts on both pathogen and host
4 acts on a variety of pathogenic micro organisms
Explanation:
Broad spectrum antibiotics are those antibiotics that effective against both gram-positive and Gram - negative bacteria.

The antibiotic penicillin has inhibitory effect through
1 dissolution of cell wall synthesis
2 inhibition of protein synthesis
3 inhibition of DNA replication
4 injury to plasma membrane
Explanation:
The antibiotic penicillin exerts its inhibitory effect by interfering with the synthesis of bacterial cell walls, weakening their structural integrity and eventually leading to bacterial cell death. This mechanism primarily affects bacteria that are actively dividing and growing.

An immunosuppressive agent produced by a microbe
1 Cyclosporin $\mathrm{A}$
2 Streptokinase
3 Penicillin
4 Statins
Explanation:
An example of an immunosuppressive agent produced by a microbe is "cyclosporin A". It is derived from the fungus Trichoderma polysporum and is used to suppress the immune system in organ transplantation and autoimmune diseases.
