BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction.

Detailed explanation-3: -Enzymes allow activation energies to be lowered. Enzymes lower the activation energy necessary to transform a reactant into a product.

Detailed explanation-4: -Some reactions require a great amount of activation energy, which acts as an energy barrier making it difficult for the reactants to come together and react. Enzymes reduce the energy needed for the reactants to come together, increasing the rate of the chemical reaction.

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.
