It will very likely change it in some way. It's impossible to be more specific without knowing what enzyme and what pH.
From the optimum conditions, an increase in pH will increase the number of OH- ions, and these will affect the charge of areas on the tertiary structure of the protein (remember that enzymes are proteins). This will cause a conformational (shape) change in the protein (enzyme), and therefore denatures it, as the active site is no longer complimentary to the substrate. This will lead to fewer Enzyme-Substrate complexes per second when using a lot of enzymes, and will decrease the rate of the enzyme reaction.

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.
Explain the effects of pH on enzyme reaction rates?
A change in pH can denature an enzyme, meaning the reaction would stop.
How does pH affect enzyme functions?
Enzymes lower the amount of Activation Energy needed for a chemical reaction, therefore speeding up the chemical reaction. For an enzyme to do this it needs to be at the correct pH, salinity, and temperature otherwise the enzyme will not be able to work. When an enzyme is in a pH that is not suitable, the enzyme's shape and structure alter and make it unable to speed up a reaction.
What are the 3 factors that can change the rate of enzyme reaction?
The first factor is Enzyme concentration or subtrate concentration.The rate of enzyme action is directly proportional to to the availability of enzyme provided the substrate concentration unlimited.Or the rate is directly proportional to the substrate concentration if enzymes are limited but if enzyme concentration is kept constant then upto the certain level the increase in substrate amount will no longer increase the rate of enzyme action. Second factor is temperature.The rate if an enzyme action is always directly proportional to the increase in temperature but upto the specific limit called as optimum temperature. Third factor is the pH value.Enzymes can work efficiently over a narrow range of pH called as Optimum pH.A minor change in pH value can denature the enzyme.
Enzymes increase the rate of a reaction by doing what?
An enzyme is a catalyst that speeds up a chemical reaction. It functions by lowering the activation energy required for a reaction to occur, and by reducing the activation energy, the reaction speeds up.
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.
What can speed up an enzyme reaction?
An increase in temperature can increase the enzymatic reactions if it is not too hot and also if the pH is within the idea range it can speed up the reaction. The pH level is usually around 7 for most enzymes.
How does adding an acid to an enzyme reaction effect the enzyme?
it alters the pH of the enzyme denaturing it leaving it unable to carry out it's role effectively or at all
What product of catalase reaction causes bubbling?
Oxygen is the product of the catalase reaction causes bubbling. pH is varied when testing the effect of pH on enzyme activity.
Explain the effects of pH on enzyme reaction rates?
A change in pH can denature an enzyme, meaning the reaction would stop.
What is varied when testing the effect of pH on enzyme activity?
pH
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.
What Factors affecting enzyme?
you can say enzyme reaction depends on ph, temp
In a enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
catalyzed reaction

What is varied when tested the effect of pH enzyme activity?
The pH is varied to effect, by its affect, this test.
If an enzyme reaction is exposed to an unfavorable pH what happens to the speed of the reaction?
It is reduced
