Cell Membrane Transport

Front

What does 'bilayer' mean in the context of cell membranes?

Back

Two layers.

Front

What is the function of receptor proteins in the cell membrane?

Back

They bind to corresponding proteins to initiate cellular signaling pathways.

Front

Which of the following is NOT part of the cell membrane: proteins, lipids, nucleic acids, or carbohydrates?

Back

Nucleic Acids.

Front

What do the purple regions represent in a diagram of the cell membrane?

Back

Proteins.

Front

What is the hydrophobic region of the cell membrane?

Back

The part of the membrane that repels water, typically composed of fatty acid tails.

Front

What are the main components of the cell membrane?

Back

Phospholipids, proteins, cholesterol, and carbohydrates.

Front

What role do phospholipids play in the cell membrane structure?

Back

They form the bilayer that provides a barrier to most water-soluble substances.

Front

How do integral proteins differ from peripheral proteins in the cell membrane?

Back

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

Front

What is the significance of cholesterol in the cell membrane?

Back

Cholesterol helps to stabilize the membrane's fluidity.

Front

What is the function of glycoproteins in the cell membrane?

Back

They play a role in cell recognition and signaling.
