Explanation:

• Glucagon is secreted when blood glucose is low. Before eating, Kai's blood glucose was likely low (he felt hungry), so glucagon was secreted by the pancreas.
• After eating (cookies which are a source of sugar), blood glucose levels rise. Insulin is secreted by the pancreas when blood glucose is high to help cells take up glucose and lower blood - sugar levels.

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.
