Question 18

24. Explain the structure of the cell memebrane. Include the two macromolecules that are embedded within it, the polarity of different parts of the membrane, and why this makes the membrane selectively permeable. You may draw and label a picture if that helps you to explain.

Answer 18

Embedded with proteins and carbohydrates that make up the phospholipid layer. The heads of the lipid are polar and hydrophilic and the tails are nonpolar and hydrophobic. The makes it selectvely permable becuase it only allows small and non polar molecules thorugh the membrane. - U1
