WebEndothermic reactions: Heat is absorbed. 1) Photosynthesis: Plants absorb heat energy from sunlight to convert carbon dioxide and water into glucose and oxygen. 2) Cooking an egg: Heat energy is absorbed from the pan to cook the egg. WebThe different kinds of reactants that are used in a chemical reaction each have their own unique effects on the flow of energy that occurs during the reaction. When bonds are broken during an endothermic reaction, energy is absorbed into the system; on the other hand, when bonds are formed during an exothermic reaction, energy is given off.
