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.
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 process by which it increases the rate of a reaction by lowering its activation energy is called catalysis.
Detailed explanation-4: -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-5: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
