Multiple choice

What is the role of efflux pumps in drug resistance?

  1. They pump antibiotics out of the bacterial cell

  2. They pump nutrients into the bacterial cell

  3. They have no role in drug resistance

  4. They pump toxins out of the bacterial cell
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Efflux pumps pump antibiotics out of the bacterial cell, reducing the concentration of antibiotics inside the cell.

Multiple choice

What is the role of biofilms in drug resistance?

  1. They protect bacteria from antibiotics

  2. They make bacteria more susceptible to antibiotics

  3. They have no role in drug resistance

  4. They make bacteria more resistant to antibiotics
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Biofilms protect bacteria from antibiotics by forming a physical barrier that prevents the antibiotics from reaching the bacteria.

Multiple choice

  1. It allows bacteria to communicate with each other and coordinate their response to antibiotics

  2. It allows bacteria to communicate with each other and coordinate their attack on antibiotics

  3. It has no role in drug resistance

  4. It allows bacteria to communicate with each other and coordinate their resistance to antibiotics
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Quorum sensing allows bacteria to communicate with each other and coordinate their response to antibiotics, including the development of drug resistance.

Multiple choice

What is the role of integrons in the spread of drug resistance?

  1. They can carry resistance genes

  2. They can carry virulence genes

  3. They can carry both resistance genes and virulence genes

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
