Signal Transduction & Cell Communication

Front

What is the correct order of communication in signal transduction?

Back

Reception, Transduction, Response

Front

What does cholera interfere with in cell communication?

Back

G proteins, leading to an increase in cAMP production.

Front

What is the role of second messengers in signal transduction?

Back

They relay messages from the inside of the membrane throughout the cytoplasm.

Front

What type of signaling involves long-distance signals through hormones?

Back

Endocrine signaling.

Front

What is paracrine signaling?

Back

A form of cell communication where signals affect nearby cells.

Front

Define signal transduction.

Back

The process by which a cell responds to substances or signals from its environment.

Front

What are ligands?

Back

Molecules that bind to receptors to initiate a signal transduction pathway.

Front

What is the function of G proteins in cell signaling?

Back

They act as molecular switches that relay signals from receptors to target proteins.

Front

What is the difference between endocrine and paracrine signaling?

Back

Endocrine signaling involves hormones traveling through the bloodstream, while paracrine signaling affects nearby cells.

Front

What are the main components of a signal transduction pathway?

Back

Receptors, second messengers, and target proteins.
