Sulfonamides Quiz Questions With Answers - Quiz

2.

Sulfonamides inhibit
- DHFS
- DHFR
- DPS
- None
Correct Answer

A. DPS

Explanation

Sulfonamides act by inhibiting the bacterial enzyme dihydropteroate synthetase (DPS) in the folic acid pathway, disrupting bacterial nucleic acid synthesis. By substituting for PABA, they hinder its conversion to dihydrofolic acid. This action, on its own, is recognized as bacteriostatic.

Sulfamethoxazole + Trimethoprim is a combination of
- Co-trimazole
- Co- Trimoxazole
- Co- trimethoxazole
- None
Correct Answer

A. Co- Trimoxazole

Explanation

Co-trimoxazole, belonging to the sulfonamide class, combines trimethoprim and sulfamethoxazole. Its mechanism involves halting bacterial growth.

5.

Trimethoprim acts by inhibiting the
- Bacterial Cell wall
- Cell membrane
- DHFS
- DHFR
Correct Answer

A. DHFR

Explanation

Trimethoprim acts by inhibiting the DHFR (Dihydrofolate Reductase enzyme in bacteria. This enzyme is involved in the synthesis of tetrahydrofolic acid (THF), which is essential for the production of nucleic acids and amino acids in bacteria. By inhibiting DHFR, trimethoprim disrupts bacterial metabolism and growth, ultimately leading to the inhibition of bacterial reproduction and the treatment of bacterial infections.

Sulfonamides are structurally similar to
- Furosemide
- Acetazolamide
- Benzothiazide

7.

Which of the Sulfonamide is used topically?
- Sulphadoxime
- Dapsone
- Silver sulphadiazine
- Sulphanethoxazole
Correct Answer

A. Silver sulphadiazine

Explanation

Silver sulfadiazine is a sulfonamide that is used topically. It is commonly used as a topical cream in the treatment of burn wounds and certain skin infections. The silver component of the compound has antimicrobial properties, and the sulfadiazine component helps prevent or treat bacterial infections in the affected areas.

8.

Sulphadiazine is an example of
- Antibiotic
- Short-acting sulpha drug
- Intermediate
- None
Correct Answer

A. Antibiotic

Explanation

Sulfadiazine is an example of an antibiotic. It is a synthetic compound belonging to the class of drugs known as sulfonamides. Sulfadiazine is commonly used to treat various bacterial infections and is particularly effective against urinary tract infections, certain types of pneumonia, and other bacterial conditions. It works by inhibiting the growth of bacteria and is often used in combination with other antibiotics for more effective treatment.

9.

Sulphonamide is structurally and chemically related to...
- GABA
- PABA
- Both
- None
Correct Answer

A. PABA

Explanation

Sulphonamide is structurally and chemically related to PABA (Para-aminobenzoic acid). PABA is a component of folic acid, which is essential for the synthesis of nucleic acids (DNA and RNA) in bacteria. Sulphonamides are antimicrobial agents that work by interfering with the bacterial synthesis of folic acid, leading to the inhibition of bacterial growth and the treatment of bacterial infections. GABA (Gamma-Aminobutyric Acid) is a neurotransmitter in the central nervous system and is not directly related to sulphonamides.
