Typically, the signaling process involves three components: the signal, the receptor, and the effector. [citation needed] In biology, signals are mostly chemical in nature, but can also be physical cues such as pressure, voltage, temperature, or light. Chemical signals are molecules with the ability to bind and activate a specific receptor.
Chemical signalling may refer to: Chemical signalling between cells, or cell signalling; Chemical signalling between plants, or plant communication;
A semiochemical, from the Greek σημεῖον (semeion), meaning "signal", is a chemical substance or mixture released by an organism that affects the behaviors of other individuals. [1] Semiochemical communication can be divided into two broad classes: communication between individuals of the same species (intraspecific) or communication ...
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events. Proteins responsible for detecting stimuli are generally termed receptors , although in some cases the term sensor is used. [ 1 ]
Biosignals may also refer to any non-electrical signal that is capable of being monitored from biological beings, such as mechanical signals (e.g. the mechanomyogram or MMG), acoustic signals (e.g. phonetic and non-phonetic utterances, breathing), chemical signals (e.g. pH, oxygenation) and optical signals (e.g. movements).
Biocommunication of animals may include vocalizations (as between competing bird species), or pheromone production (as between various species of insects), [4] chemical signals between plants and animals (as in tannin production used by vascular plants to warn away insects), and chemically mediated communication between plants [5] [6] and ...
In cellular biology, paracrine signaling is a form of cell signaling, a type of cellular communication in which a cell produces a signal to induce changes in nearby cells, altering the behaviour of those cells.
[6] [7] [8] The basic mechanism of mechanotransduction involves converting mechanical signals into electrical or chemical signals. Some biological machines. In this process, a mechanically gated ion channel makes it possible for sound, pressure, or movement to cause a change in the excitability of specialized sensory cells and sensory neurons. [9]
