Detailed explanation-1: -An enzyme is a biological catalyst, a substance that increases the rate of a chemical reaction without being changed or consumed in the reaction.
Detailed explanation-2: -An enzyme is a biological catalyst and is almost always a protein. It speeds up the rate of a specific chemical reaction in the cell. The enzyme is not destroyed during the reaction and is used over and over.
Detailed explanation-3: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells.
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.
