Detailed explanation-1: -In this case, the products have more free energy than the reactants. Thus, the products of these reactions can be thought of as energy-storing molecules. These chemical reactions are called endergonic reactions and they are non-spontaneous.

Detailed explanation-2: -An endergonic reaction is one that requires free energy to proceed. An example of an endergonic reaction of biological interest is photosynthesis. Photosynthetic organisms conduct this reaction by using solar photons to drive the reduction of carbon dioxide to glucose and the oxidation of water to oxygen.

Detailed explanation-3: -In an exergonic reaction, the reactants have more free energy than the products. Therefore, energy is released as the reaction proceeds. In an endergonic reaction, the reactants have more less energy than the products.

Detailed explanation-4: -In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products.

Detailed explanation-5: -Photosynthesis is an endothermic reaction. The source of the energy for the formation of glucose is light (radiant energy), usually from the sun. Thus, green plants have the remarkable ability to trap the energy of sunlight and use that energy to produce glucose from carbon dioxide and water.
