You Are Interrupted While Eating Some Yogurt and You Store

You are interrupted while eating some yogurt and you store the remaining 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 areas.You correctly guess that enzymes from your saliva,via the spoon,have continued digesting the yogurt in your absence.If you left the yogurt on the counter for another 24 hours,what would happen?

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 since the enzymes have plenty of substrate.Additionally,it would speed up since the enzymes are exposed to warmer temperatures.
C) The reaction will continue until half is digested and then stop because the reaction between substrate and product will be balanced.
D) The reaction will stop because you have altered the environment and denatured the enzyme.
