10. Which type of fatty acid has no double bonds? unsaturated

11. What happens to a chemical reaction when you add an enzyme? Speeds up reaction or Lower Energy Activation

12. What type of lipid prevents plants from dehydrating? wax

13. What is the monomer for making a polypeptide? Amino acid

14. What type of polysaccharide is used for energy in plants? starch

15. What is “energy of activation”? The energy needed to start a chemical reacton
