Study of chemical processes within and relating to living organisms.
Cells constantly send and receive signals to coordinate what’s happening inside the body. This can be through chemical messengers like hormones or neurotransmitters.
Cell signaling helps control growth, immune responses, and even your mood!
Signals usually bind to special proteins (receptors) on the cell surface, triggering a chain reaction inside the cell, leading to a response.
Insulin tells cells to absorb sugar from the blood.
Nerve cells transmit signals to muscles, letting you move your hand.
Cell signaling is how cells communicate and coordinate actions.
