Which of the following does NOT typically affect bacterial cell functions?

The reason D is the correct choice is because antiviral drugs specifically target viruses, not bacteria. Bacterial cell functions can be influenced by antibiotics, which disrupt processes essential for bacterial growth and reproduction. Antifungal agents can also have an impact, particularly on bacteria in a mixed infection, as they may alter the environment, thus affecting bacterial behavior.

Antimalarial drugs primarily target the life cycle of the malaria parasite, not bacteria, and their effects do not extend to changing bacterial functions directly. Hence, while antibiotics and antifungal agents can disrupt bacterial processes, antiviral drugs have no direct influence on bacterial cells since they are designed to inhibit viral replication and activity exclusively. This distinction clarifies why antiviral drugs have no significant effect on bacterial cell functions.
