Cell Communication Flashcard

Front

What is autocrine signaling?

Back

A form of chemical signaling where a cell targets itself.

Front

What is paracrine signaling?

Back

A form of chemical signaling where a cell targets a nearby cell.

Front

What is endocrine signaling?

Back

A form of chemical signaling where a cell targets a distant cell through the bloodstream.

Front

What are gap junctions?

Back

Specialized connections between adjacent cells that allow for direct communication.

Front

What is the first step of cell signaling?

Back

Reception, where the ligand binds to the receptor.

Front

Where are ligand-gated ion channels typically found?

Back

On the cell surface.

Front

What is the role of a ligand in cell signaling?

Back

A molecule that binds to a receptor to initiate a cellular response.

Front

What is signal transduction?

Back

The process by which a cell converts an external signal into a functional response.

Front

What is a receptor in cell signaling?

Back

A protein that binds to a specific ligand and initiates a cellular response.

Front

What is the difference between autocrine and paracrine signaling?

Back

Autocrine signaling targets the same cell, while paracrine signaling targets nearby cells.
