Question

Which of the following bacterial cells would best be able to survive an attack by an antibiotic? A) A bacterial cell that used its toxins to alter its DNA and resist the antibiotic . B) A bacterial cell that had a cell membrane made of ester-linked fatty acids. C) A bacterial cell that lacked receptors on its surface for that antibiotic . D) A bacterial cell that was going through binary fission when the antibiotic appeared

Answer 1

The correct answer would be option C.

Antibiotic resistance refers to the ability of the microbes to resist or reduce the effects of the antibiotics.

The antibiotic drug always requires access to enter into the bacterial cell. For example, porin channels, penicillin-binding proteins et cetera.

So, if the antibiotic receptor is not present on the surface of bacteria then the antibiotic drug would not be able to enter the bacteria and thus, the bacteria would survive the drug.

Answer 2

Out of the choices given, the following bacterial cells that would be best able to survive an attack by an antibiotic is; A bacterial cell that has a cell membrane made of ester-linked fatty acids. The correct answer is B.
