Passive Transport Review

Which of the following is a job of the cell membrane?

• Regulates which materials enter and leave the cell.
• Breaks apart lipids, carbohydrates, and proteins from foods.
• Stores water, salt, proteins, and carbohydrates.
• Keeps the cell wall in place.

Diffusion is the movement of molecules from

• an area of equilibrium to an area of high concentration.
• an area of low concentration to an area of high concentration.
• an area of high concentration to an area of high concentration.
• an area of high concentration to an area of low concentration.
