5.
build body structures (hair, nails, cartilage)
transport gasses (hemoglobin)
movement (muscle fibers)
defense (antibodies)
regulation of cell functions (hormones and enzymes)

6. break down polymers we eat into monomers that can be absorbed and used by the body

7.
caused by the attraction between water molecules (hydrogen bonds)
high surface tension allows insects to walk on water

8.
A substance on which an enzyme acts during a chemical reaction.

9.
the place on the enzyme where the substrate attaches-- docking station
