signaaliteede
Signaaliteede, known in English as signal transduction, is the process by which a cell responds to an external signal. This process involves a series of molecular events that translate a stimulus from outside the cell into a specific cellular response. These signals can originate from hormones, neurotransmitters, growth factors, or even environmental changes like light or temperature.
The initial step in a signal transduction pathway is the binding of a signaling molecule, or ligand,
These cascading reactions amplify the initial signal, allowing a small external stimulus to elicit a significant
