Vedclass · Answer

(A) The cell membrane is composed of a lipid bilayer where the lipids are arranged with their hydrophobic tails facing inward and hydrophilic heads facing outward.This arrangement is crucial because the hydrophobic tails consist of non-polar saturated hydrocarbons,which are insoluble in water.By pointing inward,these tails are shielded from the aqueous environment (water) present both inside and outside the cell.Therefore,both the Assertion and the Reason are correct,and the Reason provides the correct explanation for the arrangement described in the Assertion.

$A$: Lipids are arranged within the cell membrane with the hydrophobic tails towards the inner part.
$R$: This ensures that the non-polar tail of saturated hydrocarbons is protected from the aqueous environment.
