How does temperature and pH affect amylase activity and why?

Answer 1

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 pH

Enzymes 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 ;)

Answer 2

Yes. Amylase is an enzyme that breaks starch (a complex carbohydrate) into its simple sugar, glucose. Starch is also known as amylose. Enzyme activity is sensitive to the temperature and pH of its environment. At the wrong temperature or pH, the enzyme's structure will degrade. When this happens the active site of the enzyme changes shape and is no longer able to interact with its substrate. Here the substrate for amylase is amylose. When an enzyme looses its shape, it is described as being denatured.

Answer 3

Both temperature and pH can affect the shape and structure of the amylase enzyme, ultimately impacting its activity. Amylase works optimally at a specific temperature and pH level. Deviations from these optimal conditions can denature the enzyme, reducing its ability to catalyze reactions effectively. High temperatures or extreme pH levels can disrupt the enzyme's active site, leading to a decrease in enzyme-substrate interactions and decreased enzyme activity.
