Cell communication is the process by which cells interact and respond to signals from their environment or other cells. This involves a series of steps including signal reception, transduction, and response.
The process by which an extracellular signaling molecule activates a specific receptor located on the cell surface or inside the cell that triggers a biochemical chain of events inside the cell, leading to a cellular response.
A type of cell communication where hormones are released into the bloodstream by endocrine glands and travel throughout the body until they reach target cells with receptors for those hormones.
