  1. 3. Monomers of lipids
  2. 6. Smallest amount of a compound; made by combining atoms
  3. 10. Element that is contained in water, and, along with carbon and oxygen, makes up about 95% of living things
  4. 11. compounds consisting of a nucleoside linked to a phosphate group; they form the basic structural unit of nucleic acids such as DNA

  6. 14. a compound made up of two hydrogen atoms and one oxygen atom which is essential for life on Earth
  7. 16. The molecule on which an enzyme binds and acts
  8. 19. A liquid mixture in which the parts are uniformly distributed
  9. 21. Make up all living things
  10. 24. Smallest part of an element; basic unit of matter
  11. 26. Deoxyribonucleic acid; biomolecule sometimes called the “blueprint of life”; encodes directions for cells to follow; double stranded, appears kind of like a spiral ladder
  12. 27. _____ Acids: Encode information/instructions; examples are DNA and RNA
  13. 29. a state of balance
  14. 30. main source of energy (directly or indirectly) for most life on Earth
  15. 32. Compounds that usually don’t contain carbon, and are associated with abiotic (nonliving) things
  16. 33. a property of matter; the ability to do work

  2. 2. Active ____: Where an enzyme attaches to a substrate
  3. 4. Pure substances made of atoms
  4. 5. pH ____: Scale that shows if something is acidic, basic, or neutral; measure H ion concentration
  5. 7. Two or more chemically bonded elements; represented by chemical formulas
  6. 8. Proteins that speed up or slow down chemical reactions
  7. 9. smallest structural and functional part of an organism; all living things are made up of one or more cells
  8. 13. Compound associated with living things; also known as macromolecules or biomolecules
  9. 15. Monomers that make up carbohydrates
  10. 17. energy-carrying molecule found in the cells of all living things
  11. 18. basic building blocks of biomolecules
  12. 20. Element that is contained in water, and, along with carbon and hydrogen, makes up about 95% of living things; also inhaled in by many animals
  13. 22. A substance that increases the rate of a chemical reaction without itself undergoing a permanent change
  14. 23. ____ Acids: Organic molecules that function as the building blocks of proteins/biomolecules
  15. 25. Combination of substances that can be separated
  16. 28. Element that, along with hydrogen and oxygen, makes up about 95% of living things
  17. 31. Ribonucleic acid; reads messages carried by DNA; looks kind of like DNA, but is single-stranded
