TRUE OR FALSE? If the statement is False, please correct it.
Part I. Organic vs. Inorganic
_____1. 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. Overview of the Four main categories of organic molecules needed by organisms
_____11. The four main categories of organic molecules needed for living things include
Nucleic Acids, Proteins, Carbohydrates and Lipids.
_____12. Lipids are food nutrients used to build and repair body parts.
_____13. Proteins are food nutrients used as the body’s first energy source.
_____14. DNA and RNA are examples of carbohydrates.
_____15. RNA determines traits.
_____16. Water cools the body, carries away wastes, and mixes with chemicals in the body.
