Question

Indirect signaling involves the use of a chemical signal (such as a hormone or growth factor) that binds to a specific receptor on the surface of the target cell. This binding event triggers a cascade of intracellular events that ultimately leads to a response by the target cell. Therefore, the target cell responds to the signal when the chemical binds to a receptor.
