  2. Signal transduction - Wikipedia

    en.wikipedia.org/wiki/Signal_transduction

    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] The changes elicited by ligand binding (or signal sensing) in a receptor give rise ...

  3. Neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Neurotransmitter

    [30] [31] Many of these are co-released along with a small-molecule transmitter. Nevertheless, in some cases, a peptide is the primary transmitter at a synapse. Beta-Endorphin is a relatively well-known example of a peptide neurotransmitter because it engages in highly specific interactions with opioid receptors in the central nervous system.

  4. Cell–cell interaction - Wikipedia

    en.wikipedia.org/wiki/Cell–cell_interaction

    Cell–cell interaction. Cell–cell interaction refers to the direct interactions between cell surfaces that play a crucial role in the development and function of multicellular organisms. These interactions allow cells to communicate with each other in response to changes in their microenvironment. This ability to send and receive signals is ...

  5. Cell signaling - Wikipedia

    en.wikipedia.org/wiki/Cell_signaling

    Cell signaling. In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor ...

  6. Reuptake - Wikipedia

    en.wikipedia.org/wiki/Reuptake

    Reuptake is the reabsorption of a neurotransmitter by a neurotransmitter transporter located along the plasma membrane of an axon terminal (i.e., the pre-synaptic neuron at a synapse) or glial cell after it has performed its function of transmitting a neural impulse. Reuptake is necessary for normal synaptic physiology because it allows for the ...

  8. Intercellular communication - Wikipedia

    en.wikipedia.org/wiki/Intercellular_communication

    This type of intercellular communication within an organism is commonly referred to as cell signalling. This type of intercellular communication is typified by a small signalling molecule diffusing through the spaces around cells, [5] often relying on a diffusion gradient forming part of the signalling response.

  9. Active transport - Wikipedia

    en.wikipedia.org/wiki/Active_transport

    Active transport. In cellular biology, active transport is the movement of molecules or ions across a cell membrane from a region of lower concentration to a region of higher concentration —against the concentration gradient. Active transport requires cellular energy to achieve this movement. There are two types of active transport: primary ...
