In the fight-or-flight response, the release of epinephrine inhibits insulin secretion but also triggers glucagon secretion in the pancreas.You are investigating how this hormone could have two different effects on the pancreas.Which possibility is most likely?
A) The binding of epinephrine has different effects based on the timing of when it binds.
B) The different effects are caused by epinephrine binding to two different receptors.
C) The different effects are based on when the last meal was eaten.
D) The increased blood flow causes effects that differ based on oxygen levels.
E) The effects differ among different individuals rather than both occurring in a single individual.

Epinephrine binding to two different receptors is the most likely explanation for its dual effects on the pancreas. Epinephrine binds to beta receptors on pancreatic cells, leading to the inhibition of insulin secretion, while it binds to alpha receptors, triggering glucagon secretion. This enables the body to release glucose into the bloodstream during the fight-or-flight response, providing additional energy for the body to respond to potential threats.
