PPT-Receptors and Effectors

What are receptors and effectors and to what do they respond Starter What are the 5 senses What are the stimuli for these What detect the stimuli Stimulus a change in the environment that causes a response.

A receptor is a protein molecule usually embedded within the cell membrane with part of its structure exposed on the outside of the cell..

A cellular signal is any event that instructs a cell to change its metabolic or proliferative state. Signals are usually generated by the binding of a ligand to a complementary cell-bound receptor. Exercise 20. BI 232. Introduction and Terminology. There are many types of sense receptors in the body.. They are not uniformly distributed.
