To regulate what enters and leaves the cell.

Front

What are phospholipids composed of?

Front

What role do cholesterol molecules play in the cell membrane?

Back

They help to stabilize the membrane's fluidity.

Front

What is the fluid mosaic model?

Back

A model that describes the structure of the cell membrane as a mosaic of various components that move fluidly.

Front

What are integral proteins?

Back

Proteins that are embedded within the lipid bilayer and can span across the membrane.

Front

What are peripheral proteins?

Back

Proteins that are attached to the exterior or interior surfaces of the membrane but do not penetrate the lipid bilayer.
