AP Bio Insta-Review Topic 4.1*: Cell Communication

Front

What is endocrine signaling?

Back

Endocrine signaling is a form of cell communication where hormones are released by endocrine cells into the bloodstream to target distant cells.

Front

What type of cell releases signals in endocrine signaling?

Back

An endocrine cell.

Front

Define autocrine signaling.

Back

Autocrine signaling is a type of cell communication where a cell releases a signal that binds to receptors on its own surface.

Front

What is the receptor location for protein hormones?

Back

Membrane Bound.

Front

What is paracrine signaling?

Back

Paracrine signaling is a form of cell communication where a cell releases signals that affect nearby target cells.

Front

What type of signaling occurs when a cell affects itself?

Back

Autocrine signaling.

Front

What is synaptic signaling?

Back

Synaptic signaling is a type of communication that occurs between neurons, where neurotransmitters are released across a synapse.

Front

What is the difference between autocrine and paracrine signaling?

Back

Autocrine signaling affects the same cell that releases the signal, while paracrine signaling affects nearby cells.

Front

What type of signaling involves hormones traveling through the bloodstream?

Back

Endocrine signaling.

Front

What is the role of receptors in cell signaling?

Back

Receptors are proteins that bind to signaling molecules (ligands) and initiate a cellular response.
