The mode of action of an enzyme is:

Options

  1. ADecreasing potential energy
  2. BIncreasing activation energy
  3. CIncreasing kinetic energy
  4. DDecreasing activation energy

Correct answer

D. Decreasing activation energy

Step-by-step solution

The activation energy is the energy required to start a reaction. Enzymes are proteins that bind to a molecule, or substrate, to modify it and lower the energy required to make it react. The rate of reaction increases if the activation energy decreases.
