Question

question 1-5
which type of movement across a cell’s plasma membrane requires energy supplied by atp?

passive transport
simple diffusion
active transport
osmosis

Explanation:

To determine which membrane transport needs ATP energy:

• Passive transport (including simple diffusion, osmosis) moves substances down concentration gradients, no ATP needed.
• Active transport moves substances against gradients, requiring ATP energy for protein pumps, etc.

Answer:

Active transport (the option labeled "Active transport")
