Reaction kinetics — practice question

Butanedioate ions can be dehydrogenated to produce $\textit{trans}$-butenedioate ions. The enzyme fumarase catalyses this reaction. Why is this reaction catalysed more quickly by fumarase?

  • AFumarase is a protein.
  • BFumarase is effective at body temperature.
  • CFumarase lowers the activation energy of the dehydrogenation reaction.
  • DThe enzyme fumarase is specific for this dehydrogenation reaction.
