A change in pH can alter the ionization of the R groups of the amino acids. When the charges on the amino acids change, hydrogen bonding within the protein molecule changes and the molecule changes shape. The new shape therefore may not be effective

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
What pH do neither enzymes work in?
at a ph of 13
Which organ secrets enzymes that are active at a low pH?
The stomach secretes protease enzymes that work best at a pH of around 2.
What are the three things that effect enzymes?
Following are the factors affectingenzymes:SalinityTemperatureInhibitorsAllosteric factorspH levelSubstate concentrationCatalystEnzyme concentration
Enzymes are affected by both pH and?
temperture.
What effect enzymes activity?
Temperature, pH, substrate concentration
How does pH levels effect an enzyme?
All enxymes work at an optimum pH. Changes in pH levels could change the rate at which the enzymes work by denaturing them.
What effect does temp and pH have on enzymes?
enzymes require specific temperature and pH in order to work properly. Otherwise, the temperature or pH change their conformation or disable their ability to bind the substrate because the required electrostatic interactions might not happen under different 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.
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
What are the two environmental factors that effect the function of enzymes?
tempeture,ph, solute concentration and salt content
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.
How pH effects Stability and Activity of Enzymes?
Enzymes are very pH-sensitive. Any change in pH results in denaturing of proteins.
What is the effect of excess heat or pH on an enzyme?
it can change the shape of enzymes & active site so the enzyme is unable to work
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.
What pH do neither enzymes work in?
at a ph of 13
