Cell Membrane Transport Mechanisms Quiz

Which of the following is a passive mechanism that does not require ATP?

• Active transport

• Endocytosis

• Diffusion

• Exocytosis

What is a characteristic of physiological (active) mechanisms in cell membrane transport?

• They do not require ATP

• They involve osmosis

• They require ATP

• They include filtration

What is diffusion?

• Movement of atoms, molecules, or ions from a region of higher concentration to a region of lower concentration

• Movement of atoms, molecules, or ions from a region of lower concentration to a region of higher concentration

• Movement of atoms, molecules, or ions without any concentration gradient

• Movement of atoms, molecules, or ions only in solid substances

What happens to solutes and water when they diffuse across a membrane permeable to both?

• They remain on one side of the membrane.

• They reach equilibrium with equal concentrations on both sides.

• They become more concentrated on one side.

• They stop moving completely.

At equilibrium, what is true about the concentrations of water and solute in both compartments?

• Concentrations are higher in one compartment.

• Concentrations are lower in one compartment.

• Concentrations are equal in both compartments.

• Concentrations are zero in both compartments.

Why is facilitated diffusion considered a passive transport mechanism?

• It requires ATP

• It does not require ATP

• It involves active transport proteins

• It moves substances against the concentration gradient

What is osmosis?

• Movement of water across a selectively permeable membrane from a region of lower water concentration to a region of higher water concentration

• Movement of water across a selectively permeable membrane from a region of higher water concentration to a region of lower water concentration

• Movement of solutes across a selectively permeable membrane from a region of higher solute concentration to a region of lower solute concentration

• Movement of solutes across a selectively permeable membrane from a region of lower solute concentration to a region of higher solute concentration
