Cellular Communication in AP Biology

Definition

Cellular communication is the process by which cells send and receive signals in order to coordinate their activities within tissues and organisms. It allows cells to communicate with each other and respond appropriately to changes in their environment.

Related terms

Signaling Pathways: Signaling pathways are complex networks of molecular interactions within a cell that transmit signals from receptors at the cell surface to target molecules inside the cell.

Autocrine Signaling:

Autocrine signaling occurs when a cell secretes chemical signals that bind to its own receptors, influencing its own behavior.

Paracrine Signaling:

Paracrine signaling involves sending local chemical signals from one cell type to nearby cells, influencing their behavior.
