B. Glycolipid.
C. Glycoprotein.
D. Carbohydrate chain of glycoprotein.
E. Cholesterol.
F. Protein.
G. Protein Channel (present as a pore within the membrane).
H. And I. Phospholipid Bilayer (about 7nm).
(b) Explain how the properties of A and C cause them to be arranged in Plasma Membrane.
• Structure A is the phospholipid molecule which consists of a phosphate head and fatty acid tails. The phosphate head is charged whereas the fatty acid tails are uncharged. It’s because the head is charged is what makes it hydrophilic (water-loving). And similarly the fatty acid tails are uncharged making them hydrophobic (water-repelling).
