Chapter 6, Problem 4TY

Researchers analyzed a cell extract—a mixture of molecules isolated from a certain type of cell—and studied a chemical reaction in which a carbohydrate was broken down into smaller molecules.

When they added a protease to the cell extract, they discovered that the protease greatly inhibited the rate of the reaction. Based on this observation, you could conclude that the reaction is

  1. a. exergonic.
  2. b. endergonic.
  3. c. catalyzed by an enzyme.
  4. d. catalyzed by a ribozyme.
  5. e. Both b and c are true of this reaction.
