long range receptorsEndocrine, parcine Short Range receptorsNeuronal and Contant dependent endocrine signals (hormones)are secreted into extracellular fluids and travel via the bloodstream paracine signalinga form of cell-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behavior or differentiation of those cells. neuronal signalingAlso called synaptic, a neurotransmitter crosses synapse to target cell and starts transduction contact-dependent signalingmembrane-bound signals bind to receptors on adjacent cells seccond messengersmall (non-protein) molecules that relay signals from cell surface receptors to target molecules within cell kinase cascadeA signaling pathway in which a protein kinase is activated by phosphorylation, and in turn phosphorylates the next protein kinase in the sequence Kinase / Phosphatase works as a Molecular Toggle Switchby taking a protein in its inactive state and phosphorylating it which then causes the protein to change shape and become active. Taking off the phosphate deactivates it.
