Vedclass · Answer

(D) The correct statement is $(D)$. According to the fluid mosaic model of cell membrane structure proposed by $Singer$ and $Nicolson$ $(1972)$,the plasma membrane consists of approximately $50-60\%$ proteins and $40-50\%$ lipids. Lipids are arranged in a bilayer with the hydrophilic (polar) heads pointing outwards and the hydrophobic (non-polar) tails pointing inwards. $Na^+$ and $K^+$ ions are transported across the cell membrane primarily via active transport (e.g.,$Na^+/K^+$ pump),not passive transport. Therefore,the statement that the fluid mosaic model was proposed by $Singer$ and $Nicolson$ is the only correct statement.
