Across
  1. 2. Made from thousands of smaller molecules
  2. 4. complex macromolecule that stores and communicates genetic information
  3. 6. the specific place where a substrate binds to an enzyme
  4. 9. Minimum amount of energy needed for reactants to form products in a chemical reaction.
  5. 10. Organic compound made of amino acids joined by peptide bonds; primary building block of organisms
  6. 12. Contain one molecule of sugar
  7. 13. a subunit of nucleic acid formed from a simple sugar, a phosphate group, and a nitrogenous base
  8. 15. a large molecule formed from smaller repeating units of identical, or nearly identical, compounds linked by covalent bonds.
  9. 16. Compounds made up of carbon, hydrogen and oxygen in a ratio of 1:2:1
Down
  1. 1. Reactant to which an enzyme binds
  2. 3. A protein that acts as a biological catalyst
  3. 5. Composed of two molecules of sugar bonded together
  4. 7. carbon compound joined by peptide bonds; building block of proteins
  5. 8. hydrophobic biological molecule composed mostly of carbon and hydrogen; examples are fats, oils, and waxes
  6. 11. A compound whose atoms are held together by covalent bonds.
  7. 14. substance that speeds up a chemical reaction by reducing the activation energy but is not itself consumed in the reaction.
