Storing genetic information.

Front

What is the role of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the membrane's fluidity.

Front

What are glycolipids?

Back

Glycolipids are lipids with carbohydrate chains that play a role in cell recognition.

Front

What are glycoproteins?

Back

Glycoproteins are proteins with carbohydrate chains that assist in cell signaling and recognition.

Front

What is the primary function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is meant by 'selective permeability' of the cell membrane?

Back

Selective permeability means that the membrane allows certain substances to pass while blocking others.

Front

What is the difference between integral and peripheral proteins?

Back

Integral proteins span the membrane, while peripheral proteins are attached to the surface.
