A reaction is what happens to the body when a stimulus is applied, a response is what happens next; i.e a stimulus illicits a reaction which illicits a respose. For example, glucose in the blood (a stimulus) causes the pancreas to release insulin (a reaction), which in turn causes the cells to take up glucose from the blood (a response).

A reaction is automatic and often instinctive, driven by emotions or habits. A response, on the other hand, involves more thought and consideration before taking action. Responses are generally more deliberate and intentional than reactions.
A reaction to a change
The Hreaction is the difference between Hf, products and Hf, reactants
An endergonic reaction requires energy input to occur, while an endothermic reaction absorbs heat from its surroundings.
The enthalpy of a reaction is the heat change that occurs during a chemical reaction at constant pressure. It represents the difference in energy between the products and reactants in the reaction.
The difference between the enthalpy of the products and the enthalpy of the reactants in a chemical reaction is known as the change in enthalpy, or H. This value represents the amount of heat energy either absorbed or released during the reaction. If H is positive, the reaction is endothermic and absorbs heat. If H is negative, the reaction is exothermic and releases heat.
