Which three of the statements are true? Amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes. The tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect. Hydrophobic molecules do not readily dissolve in water in part because water molecules involved in hydration cannot participate in normal hydrogen bonding with one another. Hydrophobic molecules are individually hydrated in water, increasing the entropy of the system. Nonpolar molecules are capable of forming micelles.

Answer:

- Amphipathic (amphiphilic) lipids are the structural basis of biological bilayer membranes.  

- The tendency of water to minimize its contact with nonpolar substances is called the hydrophobic effect.  

- Hydrophobic molecules do not readily dissolve in water in part because water molecules involved in hydration cannot participate in normal hydrogen bonding with one another.

Explanation:

The cellular membranes consist of amphipathic lipids arranged in a bilayer, which maximizes both hydrophobic and hydrophilic interactions. The hydrophobic effect can be defined as the propensity of non-polar substances to aggregate themselves and thus exclude water molecules in a solution. Thus, water molecules around non-polar residues form an arrangement that reduces the entropy. Non-polar molecules are repelled and do not dissolve in water, thereby maximizing hydrogen bonding between water molecules and minimizing the contact area between water and nonpolar molecules.
