The correct answer is bâcatalyzing a series of reactions using multiple different enzymes B. Answer b is correct. The enzymes within a multienzyme complex all work on complementary reactions in which the product of one reaction supplies the substrate for the next. The correct answer is bâ C. Answer c is incorrect. Enzymes catalyze reactions by lowering the activation energy; however, this property is not unique to multienzyme complexes. The correct answer is bâ D. Answer d is incorrect. Multienzyme complexes contain more than a single enzyme and although they do lower the activation energy, that property is not unique to these complexes.
First, enzymes do not make a reaction occur that would not occur on its own, they just make it happen much faster. Second, the enzyme molecule is not permanently altered by the reaction. It may be changed transiently, but the enzyme at the end of the reaction is the same molecule it was at the beginning.
