The table below lists enzymes that function in different locations in the human body, and the temperature and pH ranges of these locations. Different enzymes
are secreted in each of the three locations. Ptyalin digests carbohydrates. Pepsin
and trypsin both digest proteins. Discuss the activity of these enzymes. In
your
answer, be sure to: state how the activity of pepsin will most likely change after it
moves with the food from the stomach to the small intestine (1)• support your
answer using data from the table [1]• state how a fever of 40°C would most likely
affect the activity of these enzymes and support your answer (1)• identify the
characteristic of enzymes that prevents ptyalin and trypsin from digesting the
same type of food
