  1. 1. weak acid that react with strong acids or bases to prevent sharp, sudden changes in pH
  2. 4. compound that releases OH- (hydroxyl) ions in solution
  3. 6. all of the chemical reactions that occur within an organism to maintain life
  4. 7. ability to move or change matter
  5. 8. ____ reaction: process that changes or transforms one set of chemicals into another
  6. 11. ____ inhibition: attach to an allosteric site and changes the shape of the enzyme therefore changing the shape of the active site
  7. 13. ____ sites: pockets in the folds on enzyme surfaces where the substrate binds.

  1. 2. ____ reactions: chemical reactions that absorb energy
  2. 3. substance that speeds the rate of the reaction by lowering the activation energy
  3. 5. substance which an enzyme acts during a chemical reaction to help lower activation energy
  4. 8. ____ inhibition: molecules sit in the active site of the enzyme and prevent the entry of the substrate
