Contemporary Examples. â 1 competition is there, of course, but I think there is enough business for everyone as long as the demand is there,â he says. Ghost Ships of the Mediterranean Barbie Latza Nadeau January 5, 2015. 2  I am fighting that quota because I am an advocate of competition.
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.
The role of the enzyme is to reduce the activation energy, by bringing specific molecules together, rather than relying on random collisions) Action on specific Substrates. Enzymes are substrate specific, meaning only one particular substrate molecule can work with one particular enzyme. This is due to the reciprocally shaped active site. Since the enzyme is never chemically alter by a reaction, it can be reused in subsequent reactions â enzyme controlled reactions are always reversible.
