B)Cell surface proteins
C)Transmembrane proteins
D)Carbohydrate chains

Question

Quizplus · Accepted Answer

Phospholipids are composed of a polar head (containing a phosphate group and glycerol) and two nonpolar fatty acid tails. This molecular structure allows for the formation of cell membranes, with the polar heads facing outwards towards the watery environment and the nonpolar tails facing inwards, forming a hydrophobic interior. Cell surface proteins and transmembrane proteins do not have this particular structure, and carbohydrate chains are also polar but do not have nonpolar fatty acid tails.
