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:

• 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
