What is the primary function of the cell membrane?

Back

To protect the cell and control the movement of substances in and out.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport requires energy to move substances against their concentration gradient.

Front

What is diffusion?

Back

The movement of molecules from an area of higher concentration to an area of lower concentration.

Front

What is the role of proteins in the cell membrane?

Back

Proteins help transport substances across the membrane and act as receptors for signaling.
