Detailed explanation-1: -Enzymes are proteins that catalyze a chemical reaction in our body. They function as a catalyst that speeds up the reaction by lowering the activation energy. The enzyme accelerates a chemical reaction without changing its equilibrium, so it is called as a biocatalyst.
Detailed explanation-2: -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-3: -Biological catalysts are called enzymes.
Detailed explanation-4: -Biocatalysts refer to proteins that drive all non-spontaneous chemical reactions in any biological system. Also known as enzymes, they are sensitive to temperature and pH, and act only on their specific reactants, unlike inorganic catalysts.
