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.

∙ 14y agoThat depends. Many enzymes will denature if the pH is too high, thus decreasing their productivity. However, if an enzyme is functional at high pH, then the enzyme will be more active.

Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and pH
What is effect of temperature on an enzyme?
Many of the enzymes in our bodies work best at body temperature. At significantly lower temperatures the substrate molecules do not have enough kinetic energy for the reaction to take place even in the presence of the enzyme. At body temperatures significantly higher than normal, the enzyme will not work well because the kinetic energy from the molecules in the solution containing the enzyme is so high, that the enzyme's shape is pulled apart to the point that the enzyme is not able to properly function.Indeed the enzyme's structure may be so disrupted or denatured that the enzyme molecule cannot return to its original shape. Indeed the danger of high fevers stems in large part from the potential damage to enzymes and other proteins from the high temperature. The optimum performance of most human enzymes is at about 37o celcius, or the temperature of the human body. Exposing enzymes to elevated temperatures can cause them to denature, which basically means they will no longer be functional. Enzymes are more active at a specific temperature. At higher temperatures they get denatured, so their structure breaks down. Same effect as pH. At lower temperatures they become inactive, in this case when they reach their optimum temperatures, they will become active again.temperature directly affects the rate of enzyme activity.On every 10 degree Centigrade rise in temperature,rate of enzyme activity doubles.but temperature affects up to its optimum range.For example:optimum temperature range of human is 37 degree centigrade.beyond this level of temperature,it can destroy the enzyme's structure and enzyme can be denatured due to fast vibration among its molecules which can lead to the bonds to break
Is temperature a factor that affects enzyme activity?
yes. at low temperature enzymes won't work as effectively, and at high temperature enzymes are denatured.
How temperature and pH affect enzyme activity?
Temperature And Enzyme Activity: Increasing temperature means the molecules gain more kinetic energy and move faster resulting in more chances of successful collisions of enzymes and substrates forming enzyme-substrate molecules.
Why do enzyme molecules change shape at high temperatures?
The rate of enzyme reactions is affected by temperature. All enzymes have an optimum temperature range in which they work most efficiently. An enzyme is most active at its optimum temperature. A temperature rise beyond this point reduces enzyme activity till it completely stops. This happens because the enzymes structure has changed, (often a loss of the correct folding of the molecule) and it's irreversiable. The change of the structe makes the enzyme become useless because it can't bind to subrates to make chemical reactions.
State one way extremely high temperatures can affect biological catalysts found in these organisms?
extremely high temperatures can decrease the rate of enzyme action very quickly ,the enzyme becomes deactivated (enzyme does not work)
How extremely high temperatures can affect biological catalysts found in organisms?
It can lower the rate of enzyme activity or stop the whole thing completely
How does temperature affects activity?
The enzyme activity increases as the temperature rises due to the substrates colliding with the enzymes' active sites more frequently at higher temperatures. However, each enzyme has an optimum temperature as high temperatures denature enzymes.
What can high blood pressure do to enzyme activity?
butts
The activity of what fat promoting enzyme is very high in the thighs and hips of women resulting in a higher percentage of fat deposition in these areas?
Lipoprotein lipase
Why might enzyme's activity decrease at very high temperatures?
Enzymes activity is affected by temperature. At a very high temperature, enzymes became denature that means they lose their original shape, which is important for them to react. Thus, enzyme activity decreases at a very high temperature.
Some factors that may influence enzyme activity?
A low temperature can slow down enzyme activity and high temperatures can denature an enzyme making it unusable. pH levels also affect enzyme activity. Every cell has an ideal temperature and 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 happens when enzyme reaches optimal temperature?
The optimal function of the enzyme is impeded and if the temperature rises too high the enzyme, mostly protein, will degrade and become useless.
How may enzymes be deactivated?
high temperature may denature enzyme activity by passing optimum temperature
What blocks enzyme activity by binding to the active site of an enzyme?
Competitive inhibitors reduce enzyme activity by binding (in competition with the enzyme's substrate) to the active site. These inhibitors may be reversible or irreversible. With reversible inhibitors, which may release the enzyme, concentrations much higher than the concentration of the substrate would be required to completely block enzyme activity, and even then one or two reactions may take place over long periods of time. With irreversible inhibitors, which permanently attach to the enzyme, enzyme activity could be completely blocked when the amount of inhibitor matches the amount of enzyme. Competitive inhibition reduces the enzymes ability to bind substrate (so it lowers the KM) but does not alter the maximum rate (very high substrate concentrations would out compete for enzyme binding).Other types of inhibitors work in other ways. Non-competitive inhibitors bind to the enzyme on a site other than the active site. These too may be reversible or irreversible. Binding does not compete with substrate, so concentrations to completely block enzyme activity do not have to be as high as reversible competitive inhibitors. Non-competitive inhibition reduces the apparent maximum rate for the enzyme.Uncompetitive inhibitors bind only when the substrate is also bound to the enzyme (they bind to the enzyme-substrate complex). Both the maximum rate and substrate binding affinities appear lower.
