In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.
Assertion : Penicillin(G) is an antihistamine.
Reason : Penicillin (G) is effective against gram positive as well as gram negative bacteria.
Answer & explanation
Correct answer: option 3
The correct answer is option 3. Both assertion and reason are wrong statement.
Let us break down why both the assertion and reason are incorrect statements:
Assertion: Penicillin (G) is an antihistamine
Penicillin G belongs to a class of medication called antibiotics. Antibiotics work by killing bacteria or stopping their growth.
Correct Function: Penicillin G specifically targets bacterial cell walls, a structure not present in human cells. This targeted action makes it effective against bacterial infections.
Antihistamines: These medications work by blocking the action of histamine, a chemical released by the body during an allergic reaction. Histamine causes allergy symptoms like runny nose, itchy eyes, and swelling.
Reason: Penicillin (G) is effective against gram positive as well as gram negative bacteria
Penicillin G is primarily effective against gram-positive bacteria.
Gram-Positive vs. Gram-Negative Bacteria: This classification refers to the structure of the bacteria's cell wall. Penicillin G disrupts the cell wall synthesis in gram-positive bacteria, making it ineffective against some gram-negative bacteria with an outer membrane offering additional protection.
Not Relevant to Antihistamines: The effectiveness against different types of bacteria is entirely unrelated to the function of antihistamines, which target human body chemistry, not bacterial cell walls.
In summary, Penicillin G is an antibiotic, not an antihistamine, and its effectiveness against bacteria doesn't explain its non-existent antihistamine properties.
