Difference between revisions of "Catalyst"

A '''catalyst''' is a substance that alters the activation energy of a [[chemical reaction]], thus facilitating its occurrence, but does not get consumed in the process.<ref>Wile, Jay L. ''Exploring Creation With Biology''. Apologia Educational Ministries, Inc. 1998.</ref> A [[protein]] that acts as a catalyst is called an [[enzyme]]. An example of catalysis is the action of Manganese oxide on the decomposition of Hydrogen Peroxide. Heterozygous catalysis occurs when catalyst and reactant(s) are in the same phase or state (e.g. both are liquid/aqueous) whereas homozyous catalyis is when they are in different phases.
