Which term describes substances that kill off or slow the growth of bacteria and other microorganisms?

• A. Antibiotics
• B. Vitamins
• C. Water
• D. Fats

Answer: (A)

Antibiotics are substances that kill bacteria or slow their growth by targeting essential processes in bacterial cells. They can be bactericidal, which kill bacteria, or bacteriostatic, which prevent bacteria from multiplying so the immune system can fight them off. This makes antibiotics the standard term for drugs that treat bacterial infections by reducing or eliminating the bacterial population. Vitamins are nutrients that support metabolic processes and overall health; they don’t function as agents that kill or inhibit bacteria. Water is essential for all life and acts as a solvent and medium for biochemical reactions, not as an antimicrobial. Fats provide energy and structural roles in cells, but they don’t have antimicrobial properties.
