Quick 10Q: Cell Communication

Front

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

Back

Reception -> Transduction -> Response

Front

How are ligands cell-specific?

Back

Each cell has different receptors to bind to the ligand.

Front

Where does the ligand bind to initiate signal transduction?

Back

Receptor

Front

What is a potential response for the cell in signal transduction?

Back

Transcription Factor

Front

Can more than one ligand bind to the same receptor?

Back

True

Front

What is a ligand?

Back

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

Front

What role do receptors play in cell communication?

Back

Receptors are proteins that receive and bind to ligands, triggering a response in the cell.

Front

What is signal transduction?

Back

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

Front

What is a phosphorylation cascade?

Back

A series of chemical reactions in a cell where enzymes add phosphate groups to proteins, often amplifying a signal.

Front

What is the function of transcription factors in cell signaling?

Back

Transcription factors regulate the expression of specific genes in response to signaling pathways.
