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

What is the normal pH level of the duodenum?
The normal pH level of the Duodenum is between 7 - 8, fairly neutral. So the enzymes released can work best.
Optimum pH level for enzymes?
It depends of the enzyme. For instance. Amylase in the mouth has a higher pH than say pepsin in the stomach.
Can enzymes work over a broad range of PH levels?
Most enzymes work best at a certain pH, however there are some enzymes that can operate over a broad pH range.
What happens to enzymes at a low pH?
The activity of the enzymes depends on the specific pH needed.
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
If the pH level is increasedthan enzymatic rate will decreased?
Yes. when the pH level is too high then the enzymes will denature and become inactive. :)
Will enzyme activity be higher or lower if the pH is high?
Yes it does. Enzymes increase rate of reaction as the pH level increases but enzymes work best at optimum pH. If pH level still increase, then enzyme will become denatured and rate of reaction once again decreases.

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.
What effect has pH on enzymes?
too high or too low pH denatures the enzymes. you will get a small reaction with a base or acid. neutral pH level maximizes reactions
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.
What factors affect the activity of enzymes?
Enzymes work best in the pH and temperature that they are " designed " for. A pepsin enzyme works best in the low pH environment of the stomach, while amylase works best at mouth temperature and ~ 7 pH. Heat and out of range pH can denature enzymes and not only affect their activity but inactivate them.
What is the normal pH level of pig saliva?
The normal pH level of pig saliva is slightly acidic. The acids and enzymes in pig saliva help to start breaking down food before it is swallowed.
How pH effects Stability and Activity of Enzymes?
Enzymes are very pH-sensitive. Any change in pH results in denaturing of proteins.
How do enzyme factors affect enzyme activity?
Ph level accelerates enzymes and temperature slows the process down
What are two factors that play a key role in the efficacy of digestive enzymes?
The 2 factors are temperature and pH level.
