BIOMOLECULES AND ENZYMES

Detailed explanation-1: -An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur. A hallmark of this type of reaction is that it feels cold.

Detailed explanation-2: -Absorption is an endothermic process while adsorption is an exothermic phenomenon.

Detailed explanation-3: -Endothermic reactions are chemical reactions in which the reactants absorb heat energy from the surroundings to form products.

Detailed explanation-4: -Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Chemical reactions that absorb (or use) energy are called endothermic.
