If a molecule contains at least carbon and hydrogen, it is considered inorganic. _____2. A carbon atom can form bonds with 4 other atoms. _____3. Only living things can make organic compounds _____4. H3PO4 is an example of an organic compound. Part 2. Polymers vs. Monomers and Why Study Organic Molecules _____5. Many polymers join together to make a monomer. _____6. A polymer is bigger than a monomer. _____7. Hydrolysis breaks a polymer into its monomers. _____8. In dehydration synthesis, water is added to monomers to form a polymer. _____9. Nutrients are organic and inorganic molecules from our food. _____10. In our cells, organic nutrients provide energy and materials needed for life. Part 3.
