Explore Plasma Membrane Functions

What forms due to the two layers of phospholipids coming together?

• trilayer

• bilayer

• unilayer

An embedded protein in the cell membrane, providing a hydrophilic passageway for small, polar ions.

• carrier protein

• channel protein

• receptor protein

A property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment

• selective permeability

• hydrophilic

• hydrophobic

• selective durability

The cell membrane is mostly made of what?

• Membrane-spanning Proteins

• Surface Proteins

• Phospholipids

• Carbohydrates

The cell membrane is _______________ permeable.

• selectively

• somewhat

• physically

• ionically

are proteins that carry substances from one side of a biological membrane to the other

• carrier protein

• channel protein

• receptor protein

Located on the cell membrane surface, nucleus membrane or other cellular organelle membrane - they can bind to corresponding proteins to initiate cellular signaling pathways (reactions).

• carrier protein

• channel protein

• receptor protein
