GENERAL KNOWLEDGE

Detailed explanation-1: -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-2: -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-3: -The lowering of the activation energy of a chemical reaction increases the rate of the chemical reaction. This process is termed catalysis. The chemical substances that lower the activation energy of a chemical reaction is known as catalysts.

Detailed explanation-4: -The process of speeding up a reaction by reducing its activation energy is known as catalysis, and the factor that’s added to lower the activation energy is called a catalyst.
