Quick 10Q: Cell Communication

Front

What is the order of steps for a signal transduction pathway?

Back

Reception -> Transduction -> Response

Front

What is a secondary messenger in cell signaling?

Back

cAMP (cyclic Adenosine Monophosphate) is a common secondary messenger.

Front

How does paracrine signaling differ from hormone signaling?

Back

Hormone signaling involves the bloodstream and is long-distance, while paracrine signaling involves extracellular fluid and is short-distance.

Front

Can more than one ligand bind to the same receptor?

Back

True

Front

What is a potential response for a cell during signal transduction?

Back

Activation of a transcription factor.

Front

What is signal transduction?

Back

The process by which a cell responds to external signals through a series of molecular events.

Front

What role do receptors play in cell communication?

Back

Receptors bind to ligands and initiate signal transduction pathways.

Front

What is a ligand?

Back

A molecule that binds to a receptor to initiate a response in the cell.

Front

What is the function of a phosphorylation cascade?

Back

To amplify the signal and lead to a cellular response.

Front

What is the significance of secondary messengers?

Back

They help relay signals from receptors to target molecules inside the cell.
