Which of the following best describes bacterial toxins?

• A. Poisonous substances produced by some microorganisms
• B. Nutrients produced by bacteria
• C. Enzymes that digest proteins only
• D. Antibiotics that kill bacteria

Answer: (A)

Bacterial toxins are poisonous substances produced by some microorganisms that can harm the host. They come in forms like exotoxins, which are secreted, and endotoxins, which are part of the bacterial cell wall and released when bacteria die. This makes the description of poisonous substances produced by some microorganisms the best fit. Nutrients produced by bacteria aren’t toxins, and while some toxins are enzymes that disrupt tissues, toxin activity isn’t limited to protein digestion. Antibiotics that kill bacteria are antimicrobial compounds, not toxins that harm the host.
