Cell communication involves a cell detecting and responding to signals from other cells. Receptor molecules play an important ro
Bumek [7]

Explanation:

-the specific binding of a region of the protein to solutes or a substrate

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers or function as receptors.

These include receptor proteins that bind specifically to molecules called lingands; some also use channels which respond to chemical signals by modifying solute-specific regions that aid in regulating ion exchange, through the hydrophobic layer of the plasma membrane.

Polar compounds are forming bonds with the water on the outside of the membrane. These bonds are called ___.
Lana71 [14]

Answer:

Hydrogen Bonds

Explanation:

The arrangement of phospholipid bilayer of plasma membrane is such that ; the polar phospholipid heads  point outwards into the watery external environments. This Polar environment is Hydrophilic  or water loving, while the water- hating hydrophobic tail  region pointed inwards away from the watery medium.

This gives  the usual bilayer  shape to the plasma membrane,with the tail facing one another and heads outward.

The hydrogen bond is formed as inter molecular forces  between the hydrogen atom (positive side)of water molecule and oxygen atom (negative side)of the polar molecules e.g glucose, to form an idea dipole -dipole  force interactions,

Polar Compounds,  glucose, urea dissolved easily in hyrophilic  watery environment  to from Hydrogen bonds with water

<u>The correct answer is Hydrogen bond a dipole dipole  force</u>
