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.

∙ 15y agoNo E.g Enzymes in the stomach (e.g pepsin) work best at lower pHs, like pH 3. Enzymes in the mouth (e.g amylase, which breaks down starch) would work at higher pHs

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.
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.
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.
All enzymes function optimally at pH equals 7.4 . true or false?
Enzymes have an individual optimum pH, such as pepsin has a very low optimum pH
What are the factors affects the function of enzymes?
pH and Temperature both impact the enzyme's function.
How pH effects Stability and Activity of Enzymes?
Enzymes are very pH-sensitive. Any change in pH results in denaturing of proteins.
What conditions affects the function of enzymes?
The activity of an enzyme is affected by temperature, pH and the concentration of the substrate.
Which organelle or structure contains enzymes that function best at acidic pH values?
The lysosome
What happens if enzymes are not at optimum ph?
Enzyme become denatured.
What is the optional pH enzymes function at?
Human ones @ 7.4 (neutral at body temp).
Is an enzymes function dependent on temperature and pH?
Every enzymes has its own optimum pH and temperature, where it shows higher activity (pH:it is very specific; temperature:mostly not more than 30-37degree C). Above or below this situation the enzymes activity may differs exponentially due to the biochemical changes.
What chemical helps in providing the ideal pH for pancreatic amylase to function in the human body?
enzymes
What does the wrong pH do to the shape of an enzyme?
It will affect the shape and lead to reduced activity.
Why would a washing powder of high pH or low pH be difficult to handle?
actors such as temperature and pH can affect an enzyme's rate of reaction because enzymes are sensitive to pH and heat. Most enzymes can only function in a particular temperature or pH range, and as the enzyme works out of its normal temperature and pH range, it will denature (change in shape so that the active site no longer fits with the substrate and the enzyme can't function).
Enzymes are PH sensetive Exactly what does this mean?
They only function when the acidity or alkalinity of their environment is at a certain level.
