2. Explain how the body is able to activate an enzyme in one part of the digestive tract (i.e
stomach) and then denature the enzyme in later parts of the digestive tract ( i.e small intestine )
and at the same time activate other digestive enzymes in the small intestine to help this organ
fulfill it’s role in digestion. Think back to the pepsin and trypsin examples we looked at in class.
The graphs in the textbook used this as an example of how enzymes work in the digestive tract of
the human body. ( 1 mark )
