pH is one of major factors that affect the enzyme. Enzymes only work in a specific pH. When a pH of that region is lower or higher than the required pH, it denatures and does not work.
An example of this is amylase. Amylase is an enzyme inside a mouth that breaks down carbohydrates. The mouth is slightly basic, and that creates the perfect environment and the perfect pH that amylase works in. When amylase is taken down to the stomach where the pH is very acidic, amylase does not work anymore and the body has to rely on another enzyme that works in a more acidic environment to continue to break the food down.

∙ 14y agoThe functionality of the enzyme depends on two main factors: the pH and the temperature. If the pH is too high or too low, the enzyme will simply denature and will not function.
For example, an enzyme made in the mouth called the salivary amylase can only work in a slightly basic environment. This is why the mouth has a pH of about 7.4 (could be slightly different), it's so that amylase can digest carbohydrates. However, when it enters the stomach where the pH is around 2 (may go lower), the amylase will stop functioning and stop the digestion of carbohydrates until more amylase is released in the small intestine.

∙ 11y agoThe relationship between enzymes and potenz hydrogen (pH) is tied to enzyme function.Enzyme stability is greatest under certain environmental conditions, with pH being the primary contributing factor. Maximum enzyme activity and stability are reached at the optimum pHlevel. If the environment pH is above or below the optimum pH level, the enzyme will become inactive or less active.
The effect concerning enzymes and pH occurs at the molecular level and can alter enzymestructure and stability because enzymes are largely built from amino acids that have acidic or basic characteristics. Enzymes are highly specific by nature. An enzyme becomes activated when the appropriate substrate bonds to the enzyme like a lock and key. A chemical reactionoccurs when an enzyme is activated and the enzyme acts as a catalyst for the reaction. If thepH of the environment is extremely out of range, an enzyme can denature and lose function altogether.

What is the effect of pH upon the relative enzyme activity?
Different enzymes work best at different pH. This is refered to as the ideal pH for the enzyme. For example, the digestive enzyme trypsin works best at an acidic pH while alkaline phosphatase works best at a basic pH. Therefore, enzyme activity varies with pH and this variation depends on the enzyme being studied
What is the relationship between concentration of ions and the pH scale?
pH = -log10([H3O+]).
If an enzyme is exposed to an unfavorable pH?
Enzymes shows different enzyme activity in different pH value.If the pH is high or low than the optimum pH there is a decrease in the activity of the enzyme.But if the pH is very high or very low it may lead to the deactivation of the enzyme.
Do all enzymes perform optimally at the pH 7?
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.
How will the time taken for starch to digested in amylase be affected by the temperature?
investigate the relationship between reaction temperature and the effectiveness of the Enzyme amalayse on starch
What is the true relationship between pH and enzyme action?
The enzyme has an optimal point of pH at which the enzyme works best. For example a catalase enzyme works best in a pH of 7. When the pH changes it denatures the enzyme causing it to not be able to react with the substrate.
What pH would enzyme be most effective?
Between 8 and 10
What is the relationship between pH and viscosity?
As pH increases so does viscosity

What is the relationship between concentration of ions and the pH scale?
pH = -log10([H3O+]).
Is there a relationship between the pH of the inner thylakoid space and the pH of the stroma?
yes
At what pH would the enzyme be most effective?
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.
What is the enzyme's optimum pH?
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.
If an enzyme is exposed to an unfavorable pH?
Enzymes shows different enzyme activity in different pH value.If the pH is high or low than the optimum pH there is a decrease in the activity of the enzyme.But if the pH is very high or very low it may lead to the deactivation of the enzyme.
Temperature and can affect enzyme activity?
Ph level, enzyme concentration, substrate concentration etc
What can conclude about the relationship between the enzyme concentration and the reaction rate in the presence of excess molecules?
There is a direct relationship; as the enzyme concentration increases, the rate of reaction increases.
Do all enzymes perform optimally at the pH 7?
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.
