Question

Give the biomolecule composition of plasma membrane how are lipid molecules arranged in the membrane

Answer 1

Plasma membrane is made of phospholipid bilayer. The are arranged in this sequence p-l-l-p. where p (protein) is outermost and innermost layer while l (lipids) is the middle layer.
Membrane also contain sugar, protein and carbohydrates.
Hope this helps.

Answer 2

HLO MATE HERE IS UR ANSWER

⭐. Biochemical investigation reveal that the cell membrane possess protein and carbohydrates .

⭐. The cell membrane is composed of lipids arranged in a bilayer.

⭐. Within the membrane , the polar (hydrophilic ) head is towards the outer side and the hydrophobic tail is towards the inner part.

⭐. This ensures that non polar tail of saturated hydrocarbons is protected from the aqeous environment.

⭐. The fluidmosaic model was proposed by singer and Nicolson.

⭐. It is widely accepted model.

⭐. According to this model , the quasi - fluid nature of lipid enables lateral movement of proteins within the overall bilayer .
