Which of the following describes the given graph
Options
- AEndothermic reaction with energy A in presence of enzyme and B in absence of enzyme
- BExothermic reaction with energy A in presence of enzyme and B in the absence of enzyme
- CEndothermic reaction with energy A in absence of enzyme and B in presence of enzyme
- DExothermic reaction with energy A in absence of enzyme and B in presence of enzyme
Correct answer
B. Exothermic reaction with energy A in presence of enzyme and B in the absence of enzyme
Step-by-step solution
The potential energy of the substrate is more than the product. So it is an exothermic reaction. 'A' represents the activation energy in the presence of enzyme while 'B' in the absence of enzyme i.e., enzyme lowers down the activation energy.
