A reaction that releases energy is usually termed exothermic reaction. Energy is usually released as heat.
The energy for an endergonic reaction can come from an exergonic reaction, where energy is released. This released energy is then used to drive the endergonic reaction forward.
In an exothermic reaction heat energy is released.

exothermic reaction
This is known as a coupled reaction, where the energy released from an exergonic reaction drives an endergonic reaction by transferring energy.
When energy is released during a reaction, it is considered an exothermic reaction. This means that the reaction is giving off heat to the surroundings.
Energy is released during an exothermic reaction. The energy released was enthalpy. This includes quantities such as the attraction between molecules, the lattice energy, the chemical bonds... depends on the reaction.An endothermic reaction absorbs energy in the enthalpy of solution. It comes from the surroundings.
Energy is released in an exothermic reaction because the overall energy of the products is lower than the energy of the reactants. This difference in energy levels is released as heat to the surroundings, making the reaction exothermic.
The reaction in which energy is being released, and the overall energy change (enthalpy) is negative.
energy released by the reaction or energy absorbed.
Heat energy is released in an exothermic chemicalreaction.
