Question

hans: why is the bacterial cell wall of such great importance?
a) the cell wall is essential for bacterial viability
b) antibiotics can target the cell wall
c) the cell wall is involved in inducing disease in the infected host
d) all answers are correct

Explanation:

• Option a: The bacterial cell wall maintains cell shape and protects against osmotic lysis, which is crucial for viability.
• Option b: Many antibiotics (e.g., penicillins) target cell - wall synthesis (inhibition of peptidoglycan formation).
• Option c: Components of the cell wall (e.g., lipopolysaccharides in Gram - negative bacteria) can act as virulence factors and induce disease symptoms in the host (e.g., fever, inflammation).

Since all of the statements (a, b, and c) are correct, option d is the right choice.

Answer:

D. All answers are correct
