5867118279 | Signal transduction pathway | A series of molecular changes that converts a signal received on a target cell's surface to a specific response inside the cell | 0 | |
5867118280 | enzyme linked receptors | participate in cell signaling through extracellular ligand binding and initiation of second messenger cascades | 1 | |
5867118281 | Cell surface receptors | proteins that bind specific molocules call ligands | 2 | |
5867118282 | second messenger cascades | A multistep process that couples activation of a neurotransmitter receptor to activation of intracellular enzymes. | 3 | |
5867118283 | What is used in long distance signaling? | hormones and pheromones | 4 | |
5867118284 | Autocrine | Cell communication with own self- modify the activity of the cell which secreted them | 5 | |
5867118285 | Paracrine | hormone molecule secreted by one cell affects adjacent cells - Target cells near secreting cells (regulate neighbors) | 6 | |
5867118286 | Endocrine | Controls body functions using chemicals messengers called hormones- collection of glands that secrete hormones into the blood which regulate growth, development, and homeostasis | 7 | |
5867118287 | Hormones | Chemical substances produced in certain glands that help to regulate the way your body functions. | 8 | |
5867118288 | G-protein linked receptor | Largest group of receptors. Activates a G-protein in response to stimuli. - Up to 60% of all medicines used today influence what structures in the cell membrane | 9 | |
5867118289 | Ligand | Any molecule that bonds specifically to a receptor site of another molecule. | 10 | |
5867118290 | Ion channel linked receptors | signal molecule binds to receptor and activiates an open channel, protein informational change to allow passage through the channel. | 11 | |
5867118293 | Target cells | Cells with specific receptors in their membranes to accept specific hormones. | 12 | |
5867118294 | Direct contact signaling | molecules on the surface of one cell are recognized by receptors on the adjacent cell : gap junctions in animals, plasmodesmata in plants | 13 | |
5867118295 | Signal cascade | pathway is actually a cascade of biochemical reactions inside the cell that eventually reach the target molecule or reaction. | 14 | |
5867118296 | Pheromones | Chemical signals released by an animal that communicate information and affect the behavior of other animals of the same species. | 15 | |
5867118298 | Receptor | a protein that detects a signal molecule and performs an action in response | 16 |
