Question

question 14
the transport of certain molecules across the plasma membrane:

  • is from low concentration to high concentration.
  • requires atp
  • requires transport protein

the type of transport described above is _.
o facilitated diffusion
o simple diffusion
o osmosis
o active transport

Explanation:

Brief Explanations
  • Facilitated diffusion: Moves from high to low concentration, doesn't require ATP.
  • Simple diffusion: Moves from high to low concentration, doesn't require ATP or transport protein.
  • Osmosis: Movement of water from high to low concentration (of water), doesn't require ATP.
  • Active transport: Moves from low to high concentration, requires ATP and transport protein (as per the given characteristics in the question).

Answer:

active transport
