Formation of transition state requires high energy content of reactant molecules for alignment of reacting groups, formation of transient <a href="https://interviewquestions.tuteehub.com/tag/unstable-717952" style="font-weight:bold;" target="_blank" title="Click to know more about UNSTABLE">UNSTABLE</a> charges, rearrangements of chemical bonds etc. The energy required for formation of transition state is termed as activation energy. Enzymes enhance the rate of reaction by lowering down the activation energy of transition state.  In given graph, energy of substrate is higher than that of product <a href="https://interviewquestions.tuteehub.com/tag/reflecting-2982167" style="font-weight:bold;" target="_blank" title="Click to know more about REFLECTING">REFLECTING</a> the endothermic nature of reaction. And B is the activation energy in absence of enzyme which is lowered down to A in presence of enzyme. Therefore, the correct answer is <a href="https://interviewquestions.tuteehub.com/tag/option-25810" style="font-weight:bold;" target="_blank" title="Click to know more about OPTION">OPTION</a> C.</p></body></html>
