Explain how cell membranes and their components participate in intercellular signaling. Give a specific example of cell membrane involvement in one particular type of cellular signaling.

Answer 1

The major way of intercellular communication uses messenger substances (hormones) that are secreted by signal-producing cells and are registered by target cells. All cells produce and receive multiple, diverse signals. For example, Autocrine signals are produced by signaling cells that can also bind to the ligand that is released. This means the signaling cell and the target cell can be the same or a similar cell. This type of signaling often occurs during the early development of an organism to ensure that cells develop into the correct tissues and take on the proper function.
