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 liquefied 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 continue until all of the substrate is used and the enzyme will still remain. b) The reaction has probably stopped because the amount of saliva is small and you would have to add more saliva to continue the degradation. c) The reaction will continue indefinitely since the enzyme is not consumed by the reaction. d) The reaction has probably stopped because the yogurt has inactivated the enzyme e) The reaction will continue until half is digested and then stop because the reaction between substrate and product will be balanced.
