Question

Quizplus · Accepted Answer

Proton-driven efflux pumps are known to be used by pathogenic bacteria to expel antibiotics from the cell. This mechanism helps the bacteria to evade the effects of antibiotics and become resistant to them. Sugar or amino acid inward carriers and heme cofactors are not directly involved in antibiotic resistance mechanisms.
