Which of the following describes the given graph 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 absence 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

(b) The graph shows the exothermic reaction A in the presence of enzyme as it lowers down the activation energy substantially The B graph shows this reaction in the absence of enzyme when activation energy is quite high. Thus, option (b) is correct.
