Help with biology!?

Question

1. Imagine that you have done a gram stain and determined what antibiotic to use to kill the bacterium bacilli. If you expose the bacterium to the antibiotic, how will the antibiotic kill it?

2. If you expose the protozoan Amoeba to the antibiotic, would you expect it to kill the protozoan? Why or why not? (Hint: If you take an antibiotic, does it kill your body cells?)

Answer 1

1. The antibiotic will degrade the bacterial membrane. The surrounding solvent will flow into the cell and the cell will lyse or burst.

2. The antibiotic will not kill the protozoan since it is a eukaryote like humans. The bacteria is a prokaryote. Antibiotics target prokaryotic cells only.
