1.

FLASHCARD QUESTION

Front

What is signal transduction?

Back

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

2.

FLASHCARD QUESTION

Front

Define paracrine signaling.

Back

A form of cell communication where a cell produces a signal to induce changes in nearby cells.

3.

FLASHCARD QUESTION

Front

What is synaptic signaling?

Back

A type of signaling that occurs in the nervous system where neurotransmitters are released from a neuron to communicate with a neighboring neuron or muscle cell.

4.

FLASHCARD QUESTION

Front

Explain long-distance signaling.

Back

Communication between cells that are far apart, often involving hormones released into the bloodstream.

5.

FLASHCARD QUESTION

Front

What role do G proteins play in cell signaling?

Back

G proteins act as molecular switches that transmit signals from receptors on the cell surface to target molecules inside the cell.

6.

FLASHCARD QUESTION

Front

What is cAMP and its significance in signaling?

Back

Cyclic adenosine monophosphate (cAMP) is a secondary messenger important in many biological processes, amplifying the signal from a receptor.

7.

FLASHCARD QUESTION

Front

Define negative feedback in biological systems.

Back

A regulatory mechanism in which a change in a physiological variable triggers a response that counteracts the initial change.
