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: -Enzymes speed up a chemical reaction by lowering the activation energy required for the reactants to come together and react. Activation energy refers to the energy that is needed to trigger a chemical reaction between two or more reactants.
Detailed explanation-4: -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-5: -Enzymes are proteins They act as catalysts, which means that they make biochemical reactions happen faster than they would otherwise. Without enzymes, those reactions simply would not occur or would run too slowly to sustain life. For example, without enzymes, digestion would be impossible.
