In this graph of the change in energy during the course of a reaction, which letters(s) represents the activation energy? A and B represent the activation energy with an enzyme and c with an enzyme A and B represent the activation energy with an enzyme and c without an enzyme A and B represent the activation energy without an enzyme and C with an enzyme A and B, with A the activation energy with an enzyme and B without an enzyme A and B, with A the activation energy without an enzyme and B with an enzyme

Solution

D. correct

B showing Activation energy with an enzyme. A is activation energy without enzyme and C is overall energy released during reaction
