Answer 1

B.  III

Clarify Question
· What is the key concept addressed by the question?
        o The question is asking which type of food most greatly affects the release of insulin.
· What type of thinking is required?
        o You are being asked to evaluate three different scenarios as to their impact on insulin release.

Gather Content
· What do you know about the release of insulin? What other information is related to the question?
        o Insulin is released in the body in response to an increase in blood glucose levels. Eating a meal higher in carbohydrates would trigger more insulin to be released into the bloodstream.

· Given what you now know, what information is most likely to produce the correct answer?  
        o Panel I represents a meal higher in proteins (with the blue balls representing amino acids) and so this meal would be less likely to cause the body to release insulin. Likewise, panel II represents a meal high in fatty acids(with the larger yellow globules representing fatty acids) and so this meal would be less likely to cause the body to release insulin. The hexagon structures in panel III represent a string of glucose molecules. A meal high in these carbohydrates would trigger the greatest release of insulin in the body.

Reflect on Process
· Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
        o This question asked you to evaluate three different meals and predict which would trigger the greatest release of insulin. If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you incorrectly identify the contents of the different meals in the panels? Did you forget that insulin is associated with the digestion of glucose molecules and so the greatest amount of insulin would be release in response to meals higher in carbohydrates (glucose molecules)?
