What determines whether a cell is a target cell for a particular signal molecule?
|
phosphorylation cascade
|
|
cAMP
|
|
signal receptors
|
|
phosphatase

Explanation:
Detailed explanation-1: -In order to detect a signal (that is, to be a target cell), a neighbor cell must have the right receptor for that signal. When a signaling molecule binds to its receptor, it alters the shape or activity of the receptor, triggering a change inside of the cell.
Detailed explanation-2: -A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.
