Across
  1. 1. different enzymes have different shaped active sites (each type only works for one reaction or a very small number of reactions)
  2. 7. substrates fit into an enzyme the way a key fits into a lock
  3. 8. pH level of Amylase
  4. 11. increase in this factor usually speeds up or slows down a reaction
Down
  1. 2. the bonds holding the enzyme molecules in its shape will be disrupted by the extreme values and the enzyme denatures
  2. 3. A substance that increases the rate of chemical reaction and is not changed by the reaction
  3. 4. Proteins that are involved in all metabolic reactions
  4. 5. a region where a substrate binds and a chemical reaction takes place.
  5. 6. when the enzyme can no longer function
  6. 9. the best condition for the enzymes to carry out a chemical reaction.
  7. 10. In absence of ____ the enzyme activity is sup­pressed so much that in dry seeds the enzymes are almost inactive.
