WebAn exothermic reaction is a reaction in which energy is released in the form of light or heat. Thus in an exothermic reaction, energy is transferred into the surroundings rather than taking energy from the surroundings as in an endothermic reaction. In an exothermic reaction, the change in enthalpy ( ΔH) will be negative. WebAug 13, 2024 · Endothermic and exothermic reactions can be visually represented by energy-level diagrams like the ones in Figure 7.3. 2. In endothermic reactions, the reactants have higher bond energy ( stronger bonds) than the products. Strong bonds have … WebATP structure and hydrolysis. Adenosine triphosphate, or ATP, is a small, relatively simple molecule. It can be thought of as the main energy currency of cells, much as money is the main economic currency of human societies. The energy released by hydrolysis (breakdown) of ATP is used to power many energy-requiring cellular reactions. diverging currents
