The typical cup of green tea contains 50 mg to 150 mg of polyphenols, according to the University of Maryland Medical Center. Green tea is also available as an extract in liquid and capsules. In absence of definitive human studies, therapeutic dosage information for fatty liver disease is lacking.
exists and is an alternate of. Merge this question into. Split and merge into it. Answer by Pkchoober. Confidence votes 73. In chemistry it is called a catalyst. Enzymes decrease the activation energy needed to start a reaction.
The Activation Energy of Chemical Reactions. Only a small fraction of the collisions between reactant molecules convert the reactants into the products of the reaction. This can be understood by turning, once again, to the reaction between ClNO 2 and NO.atalysts increase the rates of reactions by providing a new mechanism that has a smaller activation energy, as shown in the figure below. A larger proportion of the collisions that occur between reactants now have enough energy to overcome the activation energy for the reaction.
