BSC 1010 Lecture Notes - Lecture 25: Phospholipid, Catabolism, Y Chromosome
Document Summary
The movement of specific molecules into a cell by the inward budding of vesicles containing proteins with receptor sites specific to the molecules being taken in; enables a cell to acquire bulk quantities of specific substances. The binding of a signal molecule to a receptor protein, activating the receptor by causing it to change shape. The conversion of a signal from outside of the cell to a form that can bring about a specific cellular response. The change in a specific cellular activity brought about by a transduced signal from outside the cell. A molecule that binds specifically to another molecule, usually a larger one. A signal receptor protein in the plasma membrane that responds to the binding of a signaling molecule by activating a g protein. A transmembrane protein containing a pore that opens or closes as it changes shape in response to a signaling molecule (ligand), allowing or blocking the flow of specific ions.
