WebIf the active site were changed, possibly by a large change in temperature or pH, the enzyme would most likely not be able to catalyze the same reactions. This is because temperature and pH can denature (or change) and enzyme's shape and therefore make it unable to bind with the same specifically shaped substrates as before. WebPeroxidase Enzyme Lab Report. Enzymes are catalysts that lower the activation energy required to start a biological reaction and affects the rate of the rection. The enzyme can become denatured when its surroundings change in temperature or pH. Molecules in the environment could also affect the enzymatic activity. north face boys zipline rain jacket

"WebIf denatured, an enzyme can no longer act as a catalyst for the reaction. Benedict’s solution is a test reagent that reacts positively with simple reducing sugars like maltose, but will not react with starch. A positive test is observed as the formation of a brownish-red cuprous oxide precipitate. A weaker positive test will be yellow to orange. " - Can absorbance change denature an enzyme
