Detailed explanation-1: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.
Detailed explanation-2: -Features of Enzyme Catalyzed Reactions Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate.
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.
