Question

same drugs not work against the microbes belonging to different group. Why ? State the mechanism of antibiotic in killing bacteria​

Answer 1

ANSWER:-

There are several types of microorganisms like bacteria, virus, protozoa etc. that cause diseases.

The resistance power of these microorganisms against drugs is different.

Drugs that can block the growth of one microbe may not be effective against another microbe.

Antibiotics like penicillin binds to the proteins that are responsible for the synthesis of cell wall in bacteria.

By binding the specific protein of bacteria penicillin blocks the biochemical pathway of cell wall synthesis in bacteria.

Antibiotics also blocks DNA synthesis, protein synthesis and ultimately results in cell death.

Answer 2

Resistant power of different microbe is different towards different drugs.

Explanation:

• There are several types of microbes like bacteria, viruses, protozoa, fungi. These microbes are genetically different from each other which is the reason that the same drug does not work on different groups of microbes.
• For example in penicillin is the drug that acts on cell walls made up of peptidoglycan and bacteria have peptidoglycan cell wall so it will work on bacteria, not on the virus.
• Drugs that act on bacteria are called antibiotics. Penicillin is the antibiotic that works on the cell wall of bacteria. It stops the synthesis of new cell walls in bacteria by blocking transpeptidation reaction which results in the killing of bacteria.
