Cell Membrane and Cell Transport

Front

What happens to a cell when the concentration of solutes outside is higher than inside and the solutes cannot enter the cell?

Back

Water will leave the cell, causing it to shrink.

Front

What is the process called when the cell membrane surrounds a particle to bring it into the cell?

Back

Endocytosis

Front

What do the purple regions in a cell membrane image typically represent?

Back

Proteins

Front

How do cells move molecules across the cell membrane against the concentration gradient?

Back

Active transport using ATP.

Front

What type of solution causes a cell to swell due to water entering?

Back

Hypotonic solution.

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is passive transport?

Back

The movement of molecules across the cell membrane without the use of energy.

Front

What is active transport?

Back

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

Front

What role do phospholipids play in the cell membrane?

Back

They form the basic structure of the cell membrane, creating a bilayer.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.
