  6. The part of an enzyme molecule where a substrate molecule attaches (by means of weak chemical bonds); typically, a pocket or groove on the enzyme's surface.
  7. An energy-requiring chemical reaction, which yields products with more potential energy than the reactants. The amount of energy stored in the products equals the difference between the potential energy in the reactants and that in the products.
  8. In comparing two solutions, the one with the greater concentration of solutes; cells in such a solution will lose water to their surroundings.
