Question

after school, kai feels hungry and tired. he finds some sugar cookies in the cabinet and finishes the whole package.
which statement best describes the role of glucagon and insulin in this scenario?
○ glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. insulin was secreted after he ate the cookies because his blood glucose was high.
○ insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. glucagon was secreted after he ate the cookies because his blood glucose was high.
○ glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. after he ate, insulin from the cookies increased his blood sugar levels.
○ insulin was secreted by his pancreas before he ate the cookies because his blood glucose was low. after he ate, glucagon from the cookies increased his blood sugar levels.

Explanation:

Glucagon is secreted when blood glucose is low (before eating, Kai was hungry, likely low blood glucose). Insulin is secreted when blood glucose is high (after eating sugar - rich cookies, blood glucose rises). Cookies contain carbohydrates (sugars), not glucagon. Insulin and glucagon are hormones, not obtained from food in this context.

Answer:

Glucagon was secreted by his pancreas before he ate the cookies because his blood glucose was low. Insulin was secreted after he ate the cookies because his blood glucose was high.
