3.1 Structure of Plasma Membrane

Report 1 / 5

Plasma membrane is selectively semi-permeable membrane that only allows small molecules to pass through it.

Large molecules require transport protein to enter the selectively semi-permeable membrane.

Which of the following statements is true on the structure of the plasma membrane?


I.		Made up from phospholipid bilayer

II.		Membrane model called the fluid mosaic model

III.		Contain transport proteins

IV.		Contain glycoproteins and glycolipids

Difficulty Level: Easy

Report 4 / 5

Which of the following are functions of glycolipids and glycoproteins on the surface of the plasma membrane?

I.		Stabilize the membrane structure

II.		Involve in cell-cell recognition

III.		Serve as receptor molecules

IV.		Transport large molecules into the cell

Difficulty Level: Medium
