Photosynthesis is an example of an endergonic reaction. It is a type of reaction in which the energy is absorbed.
Photosynthesis refers to a set of reactions that uses solar energy, water and carbon dioxide in association with the pigment chlorophyll to produce organic compounds. Solar energy is converted into chemical energy in the form of ATP and NADPH. The chemical energy in these energy rich molecules is then used for the next step of photosynthesis for the fixation of the carbon.
Thus, photosynthesis is an endergonic reaction in which the solar energy is used to fix the carbon dioxide, transferring the energy into the carbohydrates formed and releasing oxygen.
