Enzyme become denatured.
They will not function at their maximum rate
enzymes found in human bodies require different pH . like pepsin requires 1 or 2 to work, while trypsin requires 8. but overall the pH ranges from 6-8 for optimum efficiency
enzymes are proteins. when you denature a enzyme you destroy the protein structure/shape. it happens a couple of ways; 1) temperature (they have a 'optimum temperature') at certain temperatures enzymes are denatured 2) Ph, again, they have a 'optimum pH at which they work best, and certain pH levels where they are denatured. 3) Various chemicals..
I believe it's 7.3, the pH of human blood, as most enzymatic reactions occur there. However, there are special enzymes, such as the ones which are in the stomach, which work best at around a pH of 2.
Every enzyme works at its maximum rate at a specific temprature called as optimum temprature for that enzyme. AND all enzymes work at their maximum rate at narrow range of pH, called as optimum pH. A slight increase or decrease in pH causes the retardation in enzyme activity or blocks it completely.
Enzymes only work best at a certain pH. This is called an optimum pH for that enzyme. An example is the enzymes found in the stomach. The pH found there is very acidic (around pH2). If this same enzyme was in another part of the body it would either not work well or maybe not at all.The proper pH keeps the protein shape of the enzyme. Anything above or below that can stop it or even denature it. When it is denatured, it will loose the shape it has to be in to work. If you have a screw you need to remove from something, the proper screwdriver is necessary or you will strip the head (damage) the screw.
Enzymes have an individual optimum pH, such as pepsin has a very low optimum pH
enzymes found in human bodies require different pH . like pepsin requires 1 or 2 to work, while trypsin requires 8. but overall the pH ranges from 6-8 for optimum efficiency
carbohydrate digesting enzymes have an optimum pH near neutrality so is for carbohydrate digestion.

Well without specifying the parameters its impossible to say; the definition of optimum pH would be, the pH at which point the optimum results of a reaction are achieved.

Temperature, pH and time
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
It depends on what type of Enzyme. Enzymes have different optimum pH depending on the environment they work in, for example and enzyme in the stomach of a human would have a pH of about 2 but an enzyme in human saliva has an optimum pH of 5.6.
Optimum pH of most enzymes is 7. Optimum pH is pH at which enzyme shows maximum activity .It all depends to the particular enzyme you are talking about, there is no general rule. for example in human pepsin catalyse the reaction at high acidic pH (1.5 to 3) whereas trypsin has optimum pH falls between 7 to 9 (neutral to basic).
