Which of the following describes the given grapgh correctly

Options

A. Endothermic reaction with energy A in the presence of enzyme and B in the absence of enzyme
B. Exothermic reaction with energy A in the presence of enzyme and B in the absences of enzyme
C. Endothermic reaction with energy A in the absence of enzyme and B in the presence of enzyme
D. Exothermic reaction with energy A in the absence of enzyme and B in the presence of enzyme

Answer

B

Explanation

The graph A shows the exothermic reaction in the presence of enzyme as it lowers down the activation energy substantially. The graph B shows this reaction in the absence of enzyme when activation energy is quite high.
