Cell Communication Quick 10 Qs

Front

What are ligands in cell communication?

Back

Ligands are molecules that bind to receptors to initiate cell communication.

Front

What is the role of receptors in cell communication?

Back

Receptors are proteins that bind to ligands, triggering a response in the cell.

Front

What is the function of Protein Phosphatase?

Back

Protein Phosphatase is an enzyme that dephosphorylates molecules, shutting off signaling pathways.

Front

What is the function of Protein Kinase?

Back

Protein Kinase is an enzyme that phosphorylates various molecules, relaying signals inside the cell.

Front

What are the three types of cell signaling?

Back

The three types of cell signaling are endocrine, paracrine, and autocrine signaling.

Front

How does endocrine signaling work?

Back

Endocrine signaling involves hormones being released into the bloodstream to target distant cells.

Front

What is paracrine signaling?

Back

Paracrine signaling involves signals being released by cells to affect nearby cells.

Front

What is autocrine signaling?

Back

Autocrine signaling occurs when a cell releases signals that bind to its own receptors.

Front

What is signal transduction?

Back

Signal transduction is the process by which a cell converts an external signal into a functional response.

Front

What is the role of cAMP in cell signaling?

Back

cAMP acts as a secondary messenger that activates specific responses within the cell.
