Answer:
The binding of ACh to the muscarinic receptor indirectly affects the permeability of K⁺channels. This can produce hyper polarization in some organs if channels are opened, and depolarization in others if channels are closed.
Explanation:
For example, in the heart it is the beta-gamma compound that fixes to the K+ channels of heart muscle and sources them to exposed. This leads to K+ dispersion out of the cell and the cell converts into hyper polarized consequential in a reduction in heart rate. In contrast, in smooth muscle of the stomach the alpha sub unit fixes to K+ channels producing them to close. This decreases the external diffusion of K+ and the cell converts depolarized ensuing in smooth muscle contraction.
A phospholipid bilayer or lipid bilayer is a double layer of lipids in a cell membrane which has a hydrophobic and a hydrophilic part.
Hydrophobic - expelled by water
Hydrophilic - attracted to water
The layers form the cell membrane which means that it's functions are the same as the functions of a cell membrane, and are critic to the cells functioning.

Passive transport is a naturally occurring phenomenon and does not require the cell to expend energy to accomplish the movement. In passive transport, substances move from an area of higher concentration to an area of lower concentration in a process called diffusion.
