  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 t â¦ o the temperature and pH of its environment. At the wrong temperature or pH, the enzyme's structure will degrade.H 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.
