Biology definition of catalyst

WebCatalysis. Catalysis is the phenomena of altering the velocity of a chemical reaction by the presence of a catalyst. The temperature at which the catalyst activity is maximum is the optimum temp richer. The excess energy that the reactant molecules must acquire to change into the product is the activation energy. It is denoted by Ea. WebCatalytic reactions can be performed in water by employing water soluble catalysts. When the substrate is immiscible with water the reactions are performed as aqueous biphasic …
