What is a "Detect Cellular Signals"? The Most Authoritative Explanation.

What do you mean by cell signaling?

In biology, cell signaling (cell signalling in British English) or cell communication is the ability of a cell to receive, process, and transmit signals with its environment and with itself. It is a fundamental property of all cells in every living organism such as bacteria, plants, and animals.

How does a neighbor cell detect a signal?

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.

How does cell-cell signaling work?

You can learn more about how this works in the articles on ligands and receptors, signal relay, and cellular responses. Cell-cell signaling involves the transmission of a signal from a sending cell to a receiving cell. However, not all sending and receiving cells are next-door neighbors, nor do all cell pairs exchange signals in the same way.

How does a cell phone communicate?

Signal reaches a cell phone to facilitate communication in essentially the same manner that two-way radios communicate — via a signal transmitter and a signal receiver. When you’re talking on a cell phone, it converts your voice into a signal that is transmitted via radio waves to the nearest cell tower.
