Final answer:
The two main types of mechanoreceptor proteins are epithelial sodium channels and mechanically gated channels. Mechanically gated channels open due to physical deformation of the cell membrane and are involved in detecting touch and pressure.
Step-by-step explanation:
The two main types of mechanoreceptor proteins are epithelial sodium channels and mechanically gated channels.
Mechanically gated channels open due to physical deformation of the cell membrane. They are involved in detecting touch and pressure. For example, when pressure is applied to the skin, these channels open and allow ions to enter the cell. They can also open in response to temperature changes.
