AP Biology Unit 8

Polymer's split apart to form ________, by __________.

• monomers, hydrolysis

• monomers, dehydration synthesis

• amino acids, hydrolysis

• amino acids, dehydration synthesis

How do phospholipids interact with water molecules?

• Phospholipids dissolve in water.

• The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract).

• The polar heads interact with water; the nonpolar tails do not.

• Phospholipids do not interact with water because water is polar and lipids are nonpolar.
