BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Activation energy is defined as the minimum energy required by a reacting molecule to be converted into a product. The amount of activation energy is inversely proportional to the rate of reaction. Activation energy is required to start a reaction.

Detailed explanation-2: -All chemical reactions, including exothermic reactions, need activation energy to get started. Activation energy is needed so reactants can move together, overcome forces of repulsion, and start breaking bonds. activation energy: Energy needed to start a chemical reaction.

Detailed explanation-3: -In chemistry and physics, activation energy is the minimum amount of energy that must be provided for compounds to result in a chemical reaction. The activation energy (Ea) of a reaction is measured in joules per mole (J/mol), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol).
