AP Bio Insta-Review Topic 4.1*: Cell Communication

Front

What is cell communication?

Back

The process by which cells send and receive signals to coordinate their functions.

Front

What is direct signaling?

Back

A type of cell communication where cells communicate through direct contact, such as a Helper T cell binding to an antigen-presenting cell.

Front

What is paracrine signaling?

Back

A form of signaling where a cell releases a signal that affects nearby cells.

Front

What type of signaling involves a nearby cell releasing a signal?

Back

Paracrine signaling.

Front

Where are receptors for protein hormones typically located?

Back

Membrane bound.

Front

What is autocrine signaling?

Back

A type of signaling where a cell releases a signal that affects itself.

Front

What is synaptic signaling?

Back

A form of signaling that occurs between neurons, where neurotransmitters are released across a synapse.

Front

What is long-distance signaling?

Back

A type of signaling where hormones are released into the bloodstream to affect distant cells.

Front

What is the role of ligands in cell signaling?

Back

Ligands are molecules that bind to receptors to initiate a signaling cascade.

Front

What is the difference between local and long-distance signaling?

Back

Local signaling affects nearby cells, while long-distance signaling affects cells that are far away.
