AP Cell Communication

Front

What is a signaling molecule in cell communication?

Back

Ligand

Front

Do all cells have the same response to the same signal?

Back

False

Front

What is programmed cell death known as?

Back

Apoptosis

Front

How is a cellular response terminated?

Back

Separate the ligand and receptor

Front

Have we discovered a vast majority of cell surface receptor proteins?

Back

False

Front

What is the role of a receptor in cell communication?

Back

To bind to signaling molecules (ligands) and initiate a cellular response.

Front

What is the difference between autocrine and paracrine signaling?

Back

Autocrine signaling involves a cell responding to signals it produces itself, while paracrine signaling involves signals affecting nearby cells.

Front

What is signal transduction?

Back

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

Front

What is the function of G-protein coupled receptors (GPCRs)?

Back

They transmit signals from outside the cell to the inside by activating G-proteins.

Front

What is the significance of second messengers in cell signaling?

Back

They amplify the signal and help propagate the response within the cell.
