Question

identify the components of the plasma membrane. instructions: match labels a, b, c, d, e, f (from the plasma membrane diagram) to the following components: hydrophobic nonpolar fatty acid tails, hydrophilic polar phosphate head, peripheral protein, phospholipid bilayer, cholesterol, channel protein.

Explanation:

To identify the components of the plasma membrane:

• A: The phospholipid bilayer is the basic structure of the plasma membrane, composed of two layers of phospholipids. So A matches "Phospholipid bilayer".
• B: The hydrophobic nonpolar fatty acid tails are the inner part of the phospholipid, away from water. So B matches "Hydrophobic nonpolar fatty acid tails".
• C: Channel proteins are integral proteins that form channels for molecule transport. So C matches "Channel protein".
• D: The hydrophilic polar phosphate head is the outer part of the phospholipid, facing water. So D matches "Hydrophilic polar phosphate head".
• E: Cholesterol is a lipid molecule embedded in the membrane for stability. So E matches "Cholesterol".
• F: Peripheral proteins are associated with the membrane surface. So F matches "Peripheral protein".

Answer:

A. Phospholipid bilayer
B. Hydrophobic nonpolar fatty acid tails
C. Channel protein
D. Hydrophilic polar phosphate head
E. Cholesterol
F. Peripheral protein
