The protein,lipid,and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another.Why is this the case?

Question

Quizplus · Accepted Answer

The two sides of the cell membrane face different environments and have different functions, so they require different compositions to carry out those functions effectively. For example, the extracellular side of the membrane often contains glycoproteins and glycolipids for cell recognition and signaling, while the cytoplasmic side may have protein transporters and enzymes for cellular metabolism. This asymmetry is essential for proper membrane function.
