Vedclass · Answer

(D) The energy required to initiate a reaction is known as the activation energy,$E_a$.The solid curve represents the uncatalysed reaction with an activation energy of $Z$.The dashed curve represents the enzyme-catalysed reaction with a lower activation energy of $Y$.Therefore,the reduction or lowering of the activation energy due to the presence of an enzyme is given by the difference between the two,which is $(Z - Y)$.

The diagram illustrates energy changes in an enzyme-controlled reaction. Which of the following represents the lowering of the activation energy?
