Which of the following describes the given graph correctly?
Endothermic reaction with energy A in presence of enzyme and B in absence of enzyme
Exothermic reaction with energy A in presence of enzyme and B in absence of enzyme
Endothermic reaction with energy A in absence of enzyme and B in presence of enzyme
Exothermic reaction with energy A in absence of enzyme and B in presence of enzyme
The energy of the substrate is compared to the product, this reflects the endothermic nature of the reaction. Whereas, B is the activation energy and gets lowered in the absence of an enzyme.
