Question

Study the following graph of the concept of activation energy given below. Select the correct option for stages labeled A to D.

	A	B	C	D
A	Transition state	Potential energy	Activation energy without enzyme	Activation energy with enzyme
B	Kinetic energy	Potential energy	Activation energy without enzyme	Activation energy with enzyme
C	Potential energy	Transition state	Activation energy with enzyme	Activation energy without enzyme
D	Potential energy	Transitian state	Activation energy without enzyme	Activation energy with enzyme

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (D)

In the absence of enzyme the rate of enzymatic reaction very slow and also needed more activation energy, the condition is just opposite in the presence of enzyme.
The dot line represents the transition of reactant and product.
