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 generally lower activation energy by reducing the energy needed for reactants to come together and react.

Detailed explanation-3: -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-4: -Enzymes lower the activation energy necessary to transform a reactant into a product. On the left is a reaction that is not catalyzed by an enzyme (red), and on the right is one that is (green). In the enzyme-catalyzed reaction, an enzyme will bind to a reactant and facilitate its transformation into a product.

Detailed explanation-5: -Assertion :Enzymes lower the activation energy of the reactant molecule to make its transition into product easier. Reason: Enzymes are highly substrate specific.
