When endothermic reactions absorb energy, a temperature drop is measured during the reaction. Endothermic reactions are characterized by positive heat flow (into the reaction) and an increase in enthalpy (+ÎH). Examples of Endothermic and Exothermic Processes. Photosynthesis is an example of an endothermic chemical reaction.
The metabolic terms ectotherm and endotherm respectively refer to organisms that rely largely on external heat to achieve a full working temperature, and to organisms that produce heat from within as a major factor in controlling their body temperatures. Refinetti, Roberto (2010).
