The diagram outlines the three classic stages of cell signaling proposed by Earl Sutherland.
Which stage involves the conversion of an extracellular signal into intracellular molecular events?
- A
Secretion
- Bcheck_circle
Transduction
- C
Reception
- D
Response
Explanation
Transduction converts the bound ligand signal into a series of intracellular changes (often a phosphorylation cascade) that ultimately lead to the cellular response.
