The correct pH range is + or - 0.5 of the optimum pH as the enzyme will often denature at pH's outside this range. The optimum pH varies from enzyme to enzyme as each one has different optimum conditions.
The pH in living organisms varies depending on the environment to which it is adapted. for example, most human tissues are at about pH 7 (neutral pH); however our stomachs are at pH 1 (highly acidic).

Most biochemical reactions occur when the pH is between pH 6.0 and 8.0. Buffers are necessary to keep the pH from fluctuating.

the cytoplasm is the main site for all chemical reactions within a eukaryotic cell
It is usually near 7.
To be exact about 7.2

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
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.
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
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.
Enzyme become denatured.

These can range from optimum high and low temperarures, high to low Ph concenttrations
Enzymes have an individual optimum pH, such as pepsin has a very low optimum pH

carbohydrate digesting enzymes have an optimum pH near neutrality so is for carbohydrate digestion.
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).
No, the optimum pH for an enzyme depends on the environment in which it normally works. Your stomach is an acidic environment which contains an enzyme called pepsin. This not only works better in acid environments but actually denatures (that is, totally stops working) if the pH rises above 5.0.
optimum pH is 7.3
optimum pH 5-6
Most enzymes work best at a certain pH, however there are some enzymes that can operate over a broad pH range.
Most enzymes only work in a certain pH range; pH is not dependent on the presence of enzymes, however.
