A student studying reactions with enzymes uses the graph to form a conclusion. What is the best conclusion a

student can make based on the information on the graph?

• The amount of activation energy is lower in reactions

  without enzymes.

• The amount of activation energy needed is greater in

  reactions with enzymes.

• A reaction with an enzyme lowers the activation energy

  needed.

• As the reaction continues the amount of energy needed

  increases.
