AA phospholipid bilayer with proteins
BA cellulose sheet studded with pores
CA protein lattice laid over sugars
DA single layer of fatty acid tails
Answer & Solution
Correct answer: A. A phospholipid bilayer with proteins
1. A phospholipid is a lipid molecule with two fatty acid chains and a phosphate-containing group.
2. Those phospholipids form a bilayer, not a single layer.
3. Proteins are embedded within that bilayer.
4. The result is a phospholipid bilayer with embedded proteins separating the cell interior from its surroundings.
