    When a biochemical reaction is carried out in laboratory from out-side of human body in the absence of enzyme then of reaction Obtained is \[{{10}^{-6}}\] times, then activation energy of reaction in the presence of enzyme is:         [AIPMT 2001]

    A) \[\frac{6}{RT}\]            

    B)                  P it required                  

    C) Different from \[{{E}_{a}}\] obtained in laboratory

    D) Cannot say any things

    Correct Answer: C

    Solution :

    [c] When a biochemical reaction is carried out in laboratory from outside of human body in the absence of enzyme then rate of reaction obtained is \[{{10}^{-6}}\] times than activation energy of reaction in the presence of enzyme. It is different from \[{{E}_{a}}\] obtained in laboratory because for a given chemical reaction                         \[K=A{{e}^{-Ea/RT}}\,(\text{Arrhenius}\,\text{equation})\]
