What happens to heat energy in an endothermic process?

In an endothermic process, heat energy is absorbed from the surroundings. This means that the system undergoing the reaction requires energy input in order to proceed. The absorption of heat leads to a decrease in the temperature of the surrounding environment, as energy is drawn in to facilitate the reaction. This characteristic is fundamental to endothermic reactions, which include processes like photosynthesis, where plants capture sunlight to convert carbon dioxide and water into glucose and oxygen. The absorbed heat energy is then utilized to break bonds in the reactants, enabling the formation of products and often resulting in an increase in the system's internal energy.
