Front

What is the function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is osmosis?

The diffusion of water across a selectively permeable membrane.

Front

What is the role of proteins in the cell membrane?

Back

They assist in transport, act as receptors, and provide structural support.

Front

What is active transport?

Back

The movement of molecules against their concentration gradient, requiring energy.

Front

What is the difference between passive and active transport?

Back

Passive transport does not require energy, while active transport does.
