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: -In the course of an exothermic reaction, heat flows from the system to its surroundings, and thus, gets warm. Heat is absorbed by reactants to form products. Heat is released. Heat is absorbed from the surroundings; as a result, the surroundings get cold.

Detailed explanation-3: -An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.”

Detailed explanation-4: -All chemical reactions involve energy. Energy is used to break bonds in reactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions release energy.

Detailed explanation-5: -Energy Change in Endothermic Reactions Energy must be constantly added because not enough energy is released when the products form to break more bonds in the reactants. The general equation for an endothermic reaction is: Reactants + Energy → Products. Note: H represents the change in energy.
