When a bio-chemical reaction is carried out in laboratory, outside the human body in absence of enzyme, then rate of reaction obtained is 106 times, the activation energy of reaction in the presence of enzyme is
- A6/RT
- BP is required
- Cdifferent from E obtained in laboratory
- Dcan't say anything.
View written solutionFree
Correct answer: C
From Arrhenius equation, k = Ae
–Ea/RT
The activation energy of the reaction in the
presence of enzyme is different from Ea obtained in
laboratory.
