Ruben homework ENZYMES

explain how starch is used to form glucose in the human body?

why would a PH of 13 result in no reaction when breaking down starch using amylase?

what enzyme breaks down proteins?

• amylase

• maltase

• lipase

• protease

explain how a change in PH affects enzymes and rate of reaction

explain how temperature affects enzymes and rate of reaction

match where you can find each of the following enzymes:

• saliva and pancreas

• amylase

• pancreas and small intestine

• lipase

• stomach and pancreas

• protease

A student adds a set volume of starch solution to a set volume of amylase solution at a range of different pH values. At each pH, the student times how long it takes for the amylase to break down all of the starch. At pH 6 the time taken for amylase to break down all of the starch was 50 seconds.

Calculate the rate of reaction at pH 6.
