Question

a. label the following on the lipid bilayer diagram: integral proteins, peripheral protein, glycoprotein, cholesterol, phospholipid, channel protein, carrier protein.

Explanation:

Integral proteins span the lipid bilayer. Peripheral proteins are attached to the surface. Glycoproteins have carbohydrate chains attached. Cholesterol is interspersed in the bilayer. Phospholipids form the basic structure of the bilayer. Channel proteins have a pore for molecule passage. Carrier proteins change shape to transport molecules.

Answer:

1. Integral proteins: The proteins that extend through the lipid - bilayer.
2. Peripheral proteins: The proteins attached to the inner or outer surface of the lipid - bilayer.
3. Glycoprotein: The protein with carbohydrate chains attached, usually on the outer surface.
4. Cholesterol: The small, ring - shaped molecules interspersed in the lipid - bilayer.
5. Phospholipid: The molecules that form the two - layer structure of the lipid - bilayer, with a hydrophilic head and hydrophobic tails.
6. Channel protein: The protein with a central pore for the passage of specific molecules.
7. Carrier protein: The protein that can change shape to transport molecules across the lipid - bilayer.
