Passive Transport — Molecules will move from a ______ concentration to a ______ concentration.

Three types of passive transport — Which of the following is one of the three types of passive transport?

Cells need certain ______ to stay alive.

Some substances must be ______ from the cell.

To get these substances in or out, they must pass through the ______ membrane.

The movement of molecules from an area of high concentration to an area of low concentration describes this process.

In passive transport, molecules will move ______ the concentration gradient.

______ ______: difference in the concentration of a substance.

Diffusion — Some ______ molecules can ______ through the phospholipid bilayer.

Diffusion — ______ molecules cannot pass through the phospholipid bilayer.

Diffusion — Since only small particles can pass through, we say that the plasma membrane is ______ ______.

Examples of Diffusion — Which situation illustrates diffusion?

Facilitated Diffusion — Uses a ______ protein.

Facilitated Diffusion — Helps ______ molecules move from an area of high concentration to an area of low concentration.

Facilitated Diffusion — Human example = ______ (blood sugar).

Facilitated Diffusion — Uses hormone ______ to activate the carrier protein.
