1 - $300 Which statement describes the currently accepted theory of how an enzyme and its substrate fit together? A. As the product is released, the enzyme breaks down. B. The enzyme is like a key that fits into the substrate, which is like a lock. C. The active site is permanently changed by its interaction with the substrate. D.

1 - $500 While eating a container of yogurt, you have to leave, so you store the yogurt in the refrigerator. A day later you return and find the surface of the yogurt is no longer smooth but has broken into several liquified products. You correctly guess that enzymes from your saliva, via the spoon, have continued digesting the yogurt in your absence. What will happen over time? A. The reaction will soon stop because the amount of saliva is small, and you would have to add more saliva to continue the degradation. B. The reaction will continue indefinitely since the enzyme is not consumed by the reaction. C. The reaction will continue until half is digested and then stop because the reaction between substrate and product will be balanced. D. Absolutely no degradation of the yogurt will occur naturally unless in the presence of this enzyme. B
