WebEndothermic Reaction is a chemical reaction in which the reactants absorb the heat energy from the surroundings in order to form different products. These reactions create a cooling effect, as they lower the temperature of their surrounding areas. An example of endothermic physical reactions is the melting of ice cubes as they absorb heat from the … WebThe light-dependent reactions take place in the thylakoid membrane and require a continuous supply of light energy. Chlorophylls absorb this light energy, which is converted into chemical energy through the formation of two compounds, ATP \text{ATP} ATP start text, A, T, P, end text —an energy storage molecule—and NADPH \text{NADPH} …
