Receptors, activity, division
From WikiLectures
Receptors are binding sites where a chemical signal used for signal transduction is identified. They are made up of proteinaceous substances. These substances must be able to distinguish the correct signal for a given cell. This signal can also be referred to as a first messenger, ligand or agonist. The connection of the signal to the receptor can be blocked by a blocker or antagonist. One type of signal may or may not elicit the same response. What kind of response it produces depends on the type of receptor, the mechanism of the receptor, and where the receptor is present.
