Signal Transduction & Cell Communication

Front

What is signal transduction?

Back

The process by which a cell converts an external signal into a functional response, involving reception, transduction, and response.

Front

What is the correct order of communication in signal transduction?

Back

Reception, transduction, response.

Front

What role do cell surface receptors play in cell communication?

Back

They bind to signaling molecules (ligands) and initiate the signal transduction process.

Front

What is direct signaling in plants?

Back

A form of communication that occurs through structures like gap junctions, allowing direct transfer of signals between adjacent cells.

Front

What is endocrine signaling?

Back

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

Front

What is autocrine signaling?

Back

A type of signaling where a cell secretes a signal that binds to its own receptors, affecting its own behavior.

Front

What is paracrine signaling?

Back

A type of signaling where a cell releases signals that affect nearby target cells.

Front

What are gap junctions?

Back

Specialized intercellular connections that allow direct communication between adjacent cells.

Front

What is the function of ligands in cell signaling?

Back

Ligands are signaling molecules that bind to receptors to initiate a response in the target cell.

Front

What is the significance of apoptosis signaling?

Back

It is a mechanism by which infected or damaged cells signal neighboring cells to undergo programmed cell death.
