... will be denatured and will no longer work. Only few cells can accept temperatures high than approximately 45c. Enzymes work by having an active site substrate molecules, which will join with the enzyme and a reaction will take place. The enzyme will release a product; more substrate molecules can join with the active site now. Prediction: I predict that the breakdown of starch by enzyme amylase will be rapid and will increase as the temperature increases. However when it reaches 60c the amylase will discontinue to catalyse the starch, this is because amylase is made up of protein and therefore it could be easily denaturized by heat above 60c, so it will lose its shape and will no longer be able to break down starch. I think the breakdown of starch will increase until it reaches to an optimum temperature. When the temperature increases it supply's the molecules of the ...
