BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits.

Detailed explanation-2: -Enzymes allow activation energies to be lowered. Enzymes lower the activation energy necessary to transform a reactant into a product.

Detailed explanation-3: -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.
