what effect does temperature have on amylase activity?

Answer 1

Every enzyme has a range that it works best in. Too cold or too hot will inactivate it.

Answer 2

Among the environmental factors that can influence protein folding are temperature and pH. Within limits, higher temperatures cause increased molecular motion, which allows enzymes and substrates to encounter each other more often in solution. At some point, though, rising temperature starts to have the opposite effect. Excessively high temperatures cause internal vibrations of the enzyme molecule, and weak internal bonds that are critical to the maintenance of structure begin to break. This is called thermal denaturation. The curve relating enzyme activity to reaction rate shows a peak at a point called the temperature optimum, abbreviated Topt .

Most enzymes also have a distinctive pH optimum as well. At extremes of pH, excessive amounts of H+ or OH- ions bind to the protein and alter its distribution of charged sites affecting the weak bonds that rely on such sites. This changes folding patterns and, with it, functions. (Proteins don't necessarily work best in a neutral environment, e.g. some have pH optima well above pH 7, and those may not work well at all at neutrality.)

Answer 3

Amylase is an enzyme, that is to say it is a protein. Too much temperature inactivates the enzymes

Answer 4

Yeah.. what he said...
