  1. A
    Exothermic reaction with energy A in absence of enzyme and B in presence of enzyme
  2. B
    Endothermic reaction with energy A in presence of enzyme and B in absence of enzyme
  3. C
    Exothermic reaction with energy A in presence of enzyme and B in absence of enzyme
  4. D
    Endothermic reaction with energy A in absence of enzyme and B in presence of enzyme

Solution & Step-by-step Explanation

The graph shows the potential energy of the product is lower than the substrate, indicating an exothermic reaction. B represents the high activation energy required without an enzyme, while A represents the lowered activation energy with an enzyme.
