Epinephrine, also known as adrenaline, is an amine neurohormone responsible for triggering the "fight-or-flight" response in the body. It is released by the adrenal glands in response to stress or danger, and causes increased heart rate, blood pressure, and breathing rate to prepare the body for action. Dopamine is a neurotransmitter involved in reward and motivation, while peptide hormones are a broad category of hormones that include many different types. Calmodulin is a calcium-binding protein involved in many cellular processes.
