Cell Communication Flashcards
3 Steps of Cell Signaling
Ligand
A term for an ion, a molecule, or a chemical compound that cells produce to then be attached to the receptors of the same cell or other cells to induce a response.
3 Kinds of Cell Communication
- cell-to-cell
- local
- long distance
G-Protein Cycle
Greening Cycle
Cell-to-Cell Communication
Cell communication that involved direct interactions between cells; examples include plasma-membrane signaling, immune system processes, and cell junctions like gap junctions in animals and plasmodesmata in plants.
Local Communication
A form of cell communication that involves nearby cells without direct contact, such as with paracrine signaling, or the same cell, such as in autocrine signaling.
Paracrine Signaling
A form of signaling that targets nearby cells.
Autocrine Signaling
A form of cell communication in which a cell sends out a ligand that binds to a receptor on the same cell to stimulate a response.
Endocrine Signaling
A form of long-distance signaling that uses hormones to target distant cells.
Long Distance Signaling
A form of cell communication in which cells sit at long distances from one another, such as with endocrine signaling.
