The multidrug resistant pumps in many bacterial cell membranes cause
A)bacterial chromosomal mutations.
B)synthesis of enzymes that alter drug structure.
C)removal of drugs from the cell.
D)alteration of drug receptors on cell targets.
E)All of these choices are correct.

Question

Quizplus · Accepted Answer

Multidrug resistant (MDR) pumps in bacterial cell membranes are efflux pumps that actively remove drugs from the cell, preventing the drugs from reaching their intended targets and effectively reducing their efficacy. While some bacteria can develop chromosomal mutations or synthesize enzymes that alter drug structure to resist antibiotics, MDR pumps are specific to drug efflux and do not directly cause these other resistance mechanisms. Therefore, the only correct choice among the options given is C.
