What is the similarity of G-protein receptor system and Tyrosine-kinase receptor system?

both are plasma membrane receptors located at the cell surface's membrane. both are proteins that are hydrophilic and therefore cannot cross the lipid bilayer and requires second messengers to communicate with the nucleus of cells. activation of the receptors will activate other molecules in the activating cascades and the numbers of affected molecules will increase geometrically. however, activation of such receptors will cause desensitization/adaptation of the receptors themselves. the disability to desensitize can result to serious diseases such as cancer.

What Cellular acetylcholine receptor is found in effector organs of the parasympathetic system?
muscarinic receptor
Most of the food and waste materials that move into and out of a cell pass through?
Receptor Proteins
What is the difference of g-protein receptor system and tyrosine kinase receptor?
Receptor tyrosine kinases do not require the use of second messengers while G protein-coupled receptors need.
What element detects change in a control system?
Receptor/Sensor-Recognition of the factor.
How does olfaction occur?
Within the nasal cavity, odorant molecules interact with the cilia on odorant receptor cells. The binding of odorant molecules onto receptor proteins causes a net change in the membrane permeability of the receptor cells which then causes an action potential to be generated by the receptor cell. Unlike other senses, olfaction is not redirected by the Thalmus. It instead goes directly from the afferent receptor cells to the olfactory bulb. From the olfactory bulb, the action potential is sent directly to the cerebral cortex, specifically the limbic system (this is why there is a large emotional association with smell).
Which structure of a feedback system receives output from the control center?
a receptor
What Cellular acetylcholine receptor is found in effector organs of the parasympathetic system?
muscarinic receptor

Somatic system
What structures are found in the peripheeal nervous system?
peripheral nervous system consist of nerves conveying impulses from brain to sense receptor and from sense receptor to brain.
What is a cannabinoid receptor?
A cannabinoid receptor is any of several receptors, found in the central nervous system, which bind to cannabinoids.
Most of the food and waste materials that move into and out of a cell pass through?
Receptor Proteins
What is the difference of g-protein receptor system and tyrosine kinase receptor?
Receptor tyrosine kinases do not require the use of second messengers while G protein-coupled receptors need.
