Microorganisms are capable and provide economical source of alkaline protease enzymes that are able to generate a ... WebEnzymes are biological catalysts, enhancing the speed of a chemical reaction, without being used up in the process. They are critical to lowering the amount of energy needed for a reaction to begin. To do this they lower the energy of the transition state, the unstable state that a product must pass through in order to become a reactant.
