Question

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

Answer 1

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

The correct answer is Hydrogen bond a dipole dipole  force
