· What do you know about digestion in the stomach? What other information is related to the question?
        o Digestion of carbohydrates begins in the mouth where amylase is released from salivary glands. Digestion of proteins begins in the stomach with acid and proteases like pepsin. Digestion of lipids begins in the small intestines with bile acids and lipase. Mechanical digestion occurs through peristalsis in the stomach and small intestines. With a smaller stomach smaller meals need to be eaten.

· Given what you now know, what information is most likely to produce the correct answer?
        o Carbohydrate digestion begins in the mouth and will not be affected as much by a smaller stomach. Proteins are digested in the stomach. With a smaller stomach, you would need to eat smaller portions.

        o This question asked you to apply your knowledge about digestion in the stomach to predict what would happen after gastric sleeve surgery. If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you think that proteins were not digested in the stomach? Did you think that the size of the stomach would not affect the portions of meals that could be consumed?
