Local Regulator
DEFINITION 2 a secreted moleculetht influences cells near where it is secreted TERM 3
Reception
DEFINITION 3 the target cell's detection of a signaling molecule coming from outside the cell TERM 4
Transduction
DEFINITION 4 the conversion of a signal outside a cell to a form that can bring about a specific celluar response TERM 5
Response
DEFINITION 5 the change in a specific cellular activity brought about by a transduced signal from outside the cell
TERM 6
Ligand
DEFINITION 6 a molecule that binds specifically to another molecule,usually a larger one TERM 7
Hormone
DEFINITION 7 one of many types of secreted chemicals that are formed in specialized cells, travel in body fluids, and act on specific target cells in other parts of the body, changing the target cells' functioning TERM 8
Receptor Tyrosine Kinase
DEFINITION 8 a receptor protein spanning the plasma membrane, the cytoplasmic part of which can catalyze the transfer of a phospahte group from ATP to a tyrosine on another protein. TERM 9
Ligand-Gated Ion Channel
DEFINITION 9 a tranasmebrane protein containing a pore that opens or closes as it changes shape in response to a signaling molecule, allowing or blocking the flow of specific ions; also called an ionotopic receptor
