Front

What is signal transduction?

Back

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

Front

Define paracrine signaling.

Back

A form of cell signaling where the target cell is close to the signal-releasing cell.

Front

What is the role of G proteins in cell signaling?

Back

G proteins act as molecular switches that transmit signals from receptors to target proteins.

Front

What is apoptosis and why is it important?

Back

Apoptosis is programmed cell death, crucial for maintaining homeostasis and eliminating damaged cells.

Front

Define autocrine signaling.

Back

A type of signaling where a cell targets itself, releasing signals that bind to its own receptors.
