Question

When a biochemical reaction is carried out in laboratory in
the absence of enzyme then rate of reaction obtained is 10⁻⁶
times, then activation energy of reaction in the presence of
enzyme is
(a) 6/RT
(b) different from Eₐ obtained in laboratory
(c) P is required
(d) can't say anything

Answer 1

Explanation:

(b) different from Eₐ obtained in laboratory is the correct answer hg

Answer 2

When a biochemical reaction is carried out in the laboratory in the absence of enzyme then rate of reaction obtained is 10⁻⁶ times, then activation energy of a reaction in the presence of enzyme is:

(b) different from Eₐ obtained in laboratory

• To undergo a chemical transformation or physical transport, a certain amount of energy is required to activate atoms or molecules. This energy is called activation energy

• When the enzyme is present, then the reaction is $10^{6}$ time faster. This is because that enzyme provides an alternative reaction mechanism. In this case, the activation energy is reduced.
