Chemical . bonds. are the source of this energy. . Write your answer in your. . science journal.. Quiz. 1. How . many molecules of oxygen gas in the reactant (O. 2. ) are needed to balance this equation?. CH. 4. + O. 2. → 2CO. 2. + 4H. 2. O. enzymes. . . The . substance converted by an enzyme is called a . substrate. , and a substance resulting from the conversion of the substrate is called the . product. . . The . enzyme is not consumed during the reaction catalyzed by it, so one enzyme molecule is involved in the conversion of many substrate molecules .
