Receptor- Effector Coupling. Receptor. A receptor is a protein molecule usually embedded within the cell membrane with part of its structure exposed on the outside of the cell.. The protein surface is a complicated shape containing hollows, ravines, and ridges.. The function of the sensory organ. Detect stimuli or changes in the environment. Pass the impulse to the brain for interpretation then followed by action (respond) if necessary. . Provide the ability to protects us from harm or injury. Exercise 20. BI 232.
