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.
Can the reaction of an enzyme still take place if it's shape is changed by a heavy metal or the change in it's pH level?
If an enzyme is put under certain conditions, including proximity to heavy metals, pH extremes, and temperature extremes, the enzyme will break apart. This means that the enzyme has been denatured, and will no longer work. It depends on how much the enzyme's shape has changed. This is dependent on what enzyme is in question and what conditions it was put under.
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.
How does temperature and pH affect amylase activity and why?
Anylase works best in a slightly basic pH so a very acidic pH will denaturate the enzyme making it unable to do it's job.Effects of pHEnzymes are affected by changes in pH. The most favorable pH value - the point where the enzyme is most active - is known as the optimum pH.Extremely high or low pH values generally result in complete loss of activity for most enzymes. pH is also a factor in the stability of enzymes. As with activity, for each enzyme there is also a region of pH optimal stability.In addition to temperature and pH there are other factors, such as ionic strength, which can affect the enzymatic reaction. Each of these physical and chemical parameters must be considered and optimized in order for an enzymatic reaction to be accurate and reproducible.Hope this helps ;)
What is denaturing enzyme?
enzymes are proteins. when you denature a enzyme you destroy the protein structure/shape. it happens a couple of ways; 1) temperature (they have a 'optimum temperature') at certain temperatures enzymes are denatured 2) Ph, again, they have a 'optimum pH at which they work best, and certain pH levels where they are denatured. 3) Various chemicals..
How might very low pH affect an enzyme's hydrogen bonds?
A very low pH can break the hydrogen bonds in an enzyme which causes the shape of the enzyme to change shape making the enzyme unable to do it's job. This is called "denaturation" However some enzymes such as pepsin only work in a low pH (pepsin works best in a pH of about 3) so it does depend on the enzyme.
How do pH levels affected enzyme?
It disrupts an enzymes shape and structure.
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

How are enzymes affected by changes in pH?
A change in pH or and change in temperature will change the shape of the enzyme because its proteins are denatured. Therefore, the enzyme can no longer perform its desired functions because its specific shape has been altered.
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 happens if an enzyme is at a pH significantly above or below it optimum level?
Enzyme become denatured.
What can effect how an enzyme works by changing the enzyme's shape?
Enymes can change shape when it denatures. An enzyme can denature if it's not at the pH or temperature that it's used to. A denatured enzyme can no longer function (an enzyme's funcion: to speed up/cause chemical reactions fast enough for a living thing to survive).

Will lowering the pH of lactose affect the enzyme?
Yes, it would effect the enzyme as i would become acidic. If it becomes too acidic then the shape of the active site will change and the substrate will no longer fit and therefore no reaction can take place. A low pH will denature the enzyme ( cause the protein structure to change shape)
What is it called when extreme conditions like temperatures and extreme pH values changes the shape of an enzyme?
