Cell Membrane Transport Mechanisms Quiz

Which type of passive transport involves the movement of water across a selectively permeable membrane?

• Facilitated diffusion

• Simple diffusion

• Active transport

• Osmosis

What is required for molecules to move against their concentration gradient in active transport?

• Osmosis

• Facilitated diffusion

• Simple diffusion

• Energy in the form of ATP

In primary active transport, what is directly used to transport molecules across the membrane?

• Electrochemical gradient

• Osmosis

• Transport proteins

• ATP

Which protein is involved in secondary active transport to bring glucose into the cell?

• Osmosis channel

• Facilitated diffusion protein

• Co-transporter protein

• Sodium-potassium pump

What role do sodium ions play in secondary active transport?

• They are directly transported using ATP.

• They provide energy to transport other molecules.

• They diffuse through the membrane without energy.

• They are involved in osmosis.
