Directions: For each statement, write a “C” if it best applies to the carbohydrates, “L” if it best applies to lipids, “P” if it best applies to proteins, or “N” if it best applies to nucleic acids.1. I am useful for a fast source of energy. I have involvement in the immune system (ex: antibodies). I am helpful for long term energy storage. I have a large role in muscle development. If athletes “pasta load,” they consume a lot of me.6. A mutation in DNA would initially start with me.7. I make up cell membranes.8. Enzymes,which can speed up reactions, belong in my category.10. I containelements C, H, and O and have a ring-like structure. 11. My category includes genetic material. 9. I amimportant for insulation.12. I cancontain long fatty acid chains.Directions: The following table is designed to help you organize your knowledge about biomolecules. Some of the information has been filled in for you.BiomoleculeElementsFunctionsExamplesMonomerSketchCarbohydrateLipidGlycerol +Fatty AcidMany do not consider lipids to have true monomers.ProteinNucleic AcidCircle the correct answer for each multiple choice question.Lipase, maltase, and protease are members of a group of catalysts known as-EnzymesHormonesCarbohydratesFatsWhich compound is a polysaccharide?glucosemaltase ribosestarchThe enzyme salivary amylase will act on starch, but not on protein.
