Lipid bilayer - Wikipedia
WebOne feature of phospholipids is that when they are placed in an aqueous solution, they will self-assemble into a double layer (bilayer) that resembles the bilayer of the plasma membrane. This self-assembly occurs because phospholipids are hydrophilic at one end (the phospholipid head) and hydrophobic at the other end (the phospholipid tails). WebWhich of the following would most easily pass through a phospholipid bilayer? a. the anion Cl- b. polar molecules like glucose and amino acids c. H20 d. CH4 e. the cation Na+ b. sugar Consider sweetened iced tea. Which of the following is the solute? a. ice b. sugar c. water d. the beverage itself b. It contains 10% solute and 90% solvent.
