After school, Kai feels hungry and tired. He finds some sugar cookies in the cabinet and finishes the whole package.

Which statements best describe 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.
