Reaction kinetics — practice question

Enzymes function as biological catalysts. A large number of enzymes are specific. One example of an enzyme that is specific is glucokinase. Glucokinase plays a part in the metabolism of glucose. What does specificity mean in this context?

  • AGlucokinase is most effective as a catalyst over a narrow pH range.
  • BGlucokinase is most effective as a catalyst over a narrow range of temperatures.
  • CGlucokinase only operates on a narrow range of substrate molecules.
  • DGlucokinase provides an alternative route for the reactions it catalyses.
