In the fluid mosaic model of a plasma membrane:
1. | Upper layer is non-polar and hydrophilic |
2. | The polar layer is hydrophobic |
3. | Phospholipids form a bimolecular layer in the middle part |
4. | Proteins form a middle layer |
The cell membranes are mainly composed of:
1. Phospholipids
2. Proteins
3. Fats
4. Carbohydrates
