BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.

Detailed explanation-2: -How do enzymes affect the reactions in living cells? Enzymes affect the reactions in living cells by lowering the activation energy of the reaction.

Detailed explanation-3: -Enzymes increase the rate of chemical reactions by reducing the amount of activation energy needed for reactants to start reacting. Enzymes aren’t changed or used up in the reactions they catalyze, so they can be used to speed up the same reaction over and over again.

Detailed explanation-4: -Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.

Detailed explanation-5: -The enzyme speeds up the reaction by lowering the activation energy needed for the reaction to start. Compare the activation energy with and without the enzyme. Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react.
