Question

Penicillin does not have any affect on human cells. Why?

• A. Human cells don't have cell wall.
• B. Human cells cannot be destroyed by any chemical.
• C. Human cells destroy penicillin.
• D. Human cells mimic penicillin.

Answer 1

The correct option is A Human cells don't have cell wall.

The antibiotic penicillin blocks the bacterial processes that build the cell wall. Due to the lack of cell wall, the organism dies easily. Human cells don’t have a cell-wall. So penicillin cannot have such an effect on human cells.
