HUMAN NUTRITION

Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.

Detailed explanation-2: -Enzymes perform the critical task of lowering a reaction’s activation energy-that is, the amount of energy that must be put in for the reaction to begin. Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily.

Detailed explanation-3: -Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. For example: Enzymes bring reactants together so they don’t have to expend energy moving about until they collide at random.

Detailed explanation-4: -Enzymes work as catalysts in a chemical reaction, speeding up the process by lowering the energy of activation. This means that enzymes reduce the amount of energy required to make the reaction occur, making it a faster and more efficient reaction.
