Two patients come to you for help with some digestive problems. You need to figure out what is causing the problem and prescribe an enzyme supplement for each patient using the form at the end of this page.

Patient #1 (Ralph Wiggs)

Has a difficult time digesting meat products as his stomach is usually in pain. You measure the pH of his stomach acid and it reads 6 on the pH scale.

Patient #2 (Sandra Pollak)

Has low energy levels but eats the proper foods to give her energy. You take the pH of her saliva and it reads 4 on the pH scale.

To figure out which enzymes are at work, go to the following link: http://www.bbc.co.uk/schools/gcsebitesize/science/add_aqa/enzymes/enzymes4.shtml
