Whether the ambient temperature decreases, the permeability and fluidity of plasma membrane additionally decreases. Therefore to repair returned the regular permeability and fluidity level, greater quantity of unsaturated fatty acids are synthesized and integrated into the membrane. This bended look does no longer allowed them to pack tightly with every different and consequently their presence makes the plasma membrane loose. This helps in restoring again the permeability to regular level.
