An enzyme's optimum pH is the pH (that is, degree of acidity of alkalinity) that the enzyme catalyses reactions fastest at.
If the pH varies too much from the optimum, the enzyme becomes denatured and cannot catalyse reactions any more.

Does an animal cell have a lysosome?
These are membrane bound vesicular structure formed by the process of packaging in the Golgi apparatus. The isolated lysosomal vesicles have been found to be very rich in almost all types of hydrolytic enzymes optimally active at the acidic pH. These enzymes are capable of digesting carbohydrates, proteins, lipid, and nucleic acid.
At what pH is the rate of enzyme activity the highest?
Pepsin secreted in the stomach, works at highly acidic pH and the pH could be as low as 2. The optimal pH for pepsin is thus near about 2. This pH is maintained by HCl secreted by the gastric glands in the stomach.
How does substrate concentration and pH affect enzymes?
Substrate concentration will affect enzymes because substrates are specific to enzymes. The pH will affect enzymes because certain enzymes will work better in certain pH levels.
When an animal's stomach contains enzymes that break down food into smaller molecules that the animal's cells can useenzymes perform this function by?
lowering the ph
How pH effects Stability and Activity of Enzymes?
Enzymes are very pH-sensitive. Any change in pH results in denaturing of proteins.
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
Why boiling affect the rate of photosynthesis?
Photosynthesis requires many enzymes to function. An example of one of these enzymes is rubisco, which is involved in carbon fixation to RuBP. All enzymes have a specific range of variables in which they perform optimally, like pH ranges or in this case temperature. At a boiling point temperature, it is likely photosynthesis will be nonexistent or at minimal levels. This is because at such a high temperature the enzymes can become denatured, and fail to perform. This of course is not true for all types of photosynthesis, as there are some bacteria that are able to perform photosynthesis at extreme temperatures.
Why are temperatures and pH important to enzyme function?
Enzymes function optimally at a patricular temperature and pH. If the temperature is decreased or increased, the enzyme will not function as effectively. The enzyme is most active only at a patricular temperature and pH. Hence, these two factors are very important for enzyme action.
Thermoplasma?
Grow optimally at pH of 2 -> Some species lyse at neutral pH

Are pH level and enzymes related?
Most enzymes only work in a certain pH range; pH is not dependent on the presence of enzymes, however.

Why do different enzymes have different optimum pH?
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.
How does pH affect plants growth?
becaues the plants will not have room for its root to grow
