It will only respond if it has a receptor for that signal
A cell may have a different type of receptor that can only bind to one chemical messenger. The effect of the chemical messenger on the cell is dependent on the type of receptor that it binds to. For example, acetylcholine can bind to a nicotinic cholinergic receptor on a neuromuscular junction and cause an excitatory response, but acetylcholine can also bind to a muscarinic cholinergic receptor on the heart's cardiac muscle which can be either excitatory/inhibitory.
Target cells are cells that have specific receptors for a hormone or external signal, allowing them to respond to the signal. Non-target cells do not have receptors for the hormone or signal, so they do not respond to it. Target cells are the primary sites of action for hormones, while non-target cells are unaffected by the hormone.
Paracrine signaling is characterized by a cell releasing a signal molecule into the immediate environment, where nearby cells can respond to the signal. This type of signaling allows for local communication within tissues.

The Specificity of Cell Signaling and Coordination of the Response The explanation for the specificity exhibited in cellular responses to signals: different kinds of cells have different collections of proteins. (This is because different kinds of cells turn on different sets of genes). The response of a particular cell depends on its particular collection of signal receptor proteins, relay proteins, and proteins needed to carry out the response. Two cells that respond differently to the same signal differ in one or more of the proteins that handle and respond to the signal. Although cells A, B and C all have the same receptor protein, differences in other proteins account for their differences in responses.

Not all cells respond to a signal molecule because only target cells possess specific receptors that bind to the signaling molecule. These receptors are typically proteins on the cell surface or within the cell, and they are uniquely expressed in certain cell types. Additionally, the presence of downstream signaling pathways in target cells allows them to respond appropriately to the signal, while non-target cells lack the necessary machinery to interpret or transmit the signal. This selective response ensures that only specific cells are activated, allowing for precise communication and regulation within the body.
Paracrine signaling is characterized by a cell releasing a signal molecule into the immediate environment, where nearby cells can respond to the signal. This type of signaling allows for local communication within tissues.
Cells can respond to signals by changing gene expression to alter protein production, triggering changes in cell metabolism or differentiation, or by promoting cell division or death. These responses enable cells to adapt and coordinate their activities in response to external signals.
Injector #1 output driver does not respond properly to the control signal. or Injector #2 output driver does not respond properly to the control signal. or Injector #3 output driver does not respond properly to the control signal. or Injector #4 output driver does not respond properly to the control signal. or Injector #5 output driver does not respond properly to the control signal. or Injector #6 output driver does not respond properly to the control signal.

specific receptor proteins on the surface of target cells, triggering a cellular response. This binding initiates a signaling cascade that ultimately leads to changes in the cell's behavior or function. The specificity of the interaction between the signal molecule and its receptor ensures that only the appropriate cells respond to the signal.

When the pancreatic alpha cells respond, they secrete glucagon to signal cells to break down glycogen into glucose. As cells release sugar, blood glucose concentration increases.
T cells's primary task is to activate B cells and killer T cells. The B cells searchfor antigens matching its receptors. If it finds such antigen it connects to it, and inside the B cell a triggering signal is set off.
