No. They function best at the pH corresponding to their usual/intended environment. For example, pepsin, present in the stomach, which is highly acidic, functions best at acidic pH, while trypsin, secreted into the duodenum together with basic bicarbonate, functions best at moderately basic pH. This is true also within subcellular compartments: the optimal pH of lysosomal enzymes is acidic, matching the acidic proteolytic environment inside the lysosome. That said, most enzymes present in the cytosol (~neutral) and blood (~neutral) function best around neutral pH.

Why is the range of pH fixed?
pH is a function of the concentration of hydronium ions in a water solution and theoretically can take any number, not just the traditional 1-14 range. However there are physical limits to how much of this substance can be present in a solution without precipitating and this establishes the lower limit of pH. At the other end of the scale pH can be determined mathematically from the concentration of hydroxide ions, but this too is limited to a point, setting the upper limit for pH. These limits take the allowable pH range down to about -5 and up to perhaps 20.
What might occur if pH blood level persisted outside the range?
If the pH blood level persisted outside the its normal range then the enzymes in the body will not operate and may even die This will cause the organisms to become ill or to die
What temperature and pH do enzymes like to work at?
They like to work at or near body temperature with a pH of 7. Since there is a high concentration of water in cells and water's pH is 7, it makes sense that they like 7.
What does the pH have to be to dissolve something?
Well it could be any pH because water which has a pH of 7(neutral) can dissolve things for example sugar. But if it is more acidic (a lower pH) it will probably dissolve things quicker.
Industrial applications of common ion effect?
buffer solutions are the use ful applications of common ion effect they are important for biological applications[some enzymes can only work at a specific ph,the ph of gastric juices is 1.5. chemical applications fermentations,dyeing need a maximum ph.
