2nd Year Biology Chapter 11 TestPHARMACOLOGY

Q1. Multiple choice questions (Attempt all · 10 × 1 = 10)

1. Sulfonamides are often combined with which agent to create a stronger, bactericidal combined therapy?

   1. Quinine

   2. Trimethoprim

   3. Chloroquine

   4. Beta-lactamase

2. To prevent reduced drug absorption, tetracycline should not be taken alongside:

   1. Water or juices

   2. Green leafy vegetables

   3. Dairy or iron supplements

   4. Carbohydrate-rich foods

3. Penicillin primarily works to treat infections by inhibiting the synthesis of the bacterial:

   1. Cell wall

   2. Protein structure

   3. DNA replication sequence

   4. Folate metabolism path

4. Fluoroquinolones are synthetic antibacterial agents derived as a byproduct of the synthesis of:

   1. Penicillin

   2. Tetracycline

   3. Chloroquine (quinine)

   4. Sulfanilamide

5. Which group of authorities works alongside scientists to ensure new medicines are safe for public use?

   1. Regulatory authorities

   2. Financial planners

   3. Media outlets

   4. Environmental lawyers

6. Monoclonal antibodies are considered highly affect because:

   1. Have broad spectrum action

   2. Are highly specific to antigens

   3. Do not bind to any target

   4. Are non-biological in nature

7. Unlike penicillin, tetracycline does not kill bacteria outright but stops them from growing, meaning it has a:

   1. Bacteriostatic effect

   2. Bactericidical effect

   3. Lytic effect

   4. Mutagenic effect

8. The drug discovery and development process begins with the identification of:

   1. Large manufacturing facilities

   2. Disease-causing targets

   3. Patient marketing strategies

   4. Chemical waste dump sites

9. Penicillin inhibits bacterial cell wall synthesis by interrupting the cross-linking of:

   1. Peptidoglycan (murein) chains

   2. Cellulose fibers

   3. Lipopolysaccharide grids

   4. Aminoacyl-tRNA sites

10. The ...... drugs are synthetic compounds derived from sulfanilamide:

    1. Penicillin

    2. Fluoroquinolones

    3. Sulfonamides

    4. Tetracycline
