Cell Communication

Front

What is cell communication?

Back

Cell communication is the process by which cells send and receive signals to coordinate their activities and functions.

Front

Define Autocrine signaling.

Back

Autocrine signaling is a type of cell signaling where a cell secretes a signal that binds to receptors on its own surface, affecting its own behavior.

Front

What is Paracrine signaling?

Back

Paracrine signaling involves the release of signaling molecules by a cell that affect nearby target cells.

Front

Explain Endocrine signaling.

Back

Endocrine signaling is a form of long-distance communication where hormones are released into the bloodstream to target distant cells.

Front

What is Juxtacrine signaling?

Back

Juxtacrine signaling occurs when cells communicate through direct contact, often involving membrane-bound signals.

Front

Give an example of Autocrine signaling.

Back

An example of Autocrine signaling is a cancer cell releasing growth factors that stimulate its own growth.

Front

What is an example of Direct cell communication?

Back

An example of Direct cell communication is white blood cells bumping into each other to share antigen information.

Front

How does Paracrine signaling differ from Endocrine signaling?

Back

Paracrine signaling affects nearby cells, while Endocrine signaling affects distant cells through the bloodstream.

Front

What type of signaling is like talking on the phone?

Back

Endocrine signaling is like talking on the phone, as it involves long-distance communication.

Front

What is the role of signaling molecules in cell communication?

Back

Signaling molecules are chemicals that transmit information between cells, triggering responses in target cells.
