Detailed explanation-1: -The energy required to reach the transition state (the activation energy) constitutes a barrier to the progress of the reaction, limiting the rate of the reaction. Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.
Detailed explanation-2: -Enzymes are biological catalysts that speed up biochemical reactions. Enzymes are extremely efficient in speeding up reactions. They can catalyze up to several million reactions per second. Enzymes are involved in most of the biochemical reactions that take place in organisms.
Detailed explanation-3: -The answer is enzymes. 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-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.
Detailed explanation-5: -An enzyme is a biological catalyst, a substance that increases the rate of a chemical reaction without being changed or consumed in the reaction.
