    Carrier molecules facilitating transport across cell membrane are

    Which of the following features is not true for facilitated transport across the cell membrane ?

    Read the following statements carefully - (A) The lipid component of the plasma membrane mainly consists of phosphoglycerides. (B) Polar molecules can pass through the lipid bilayer of the plasma membrane, therefore they do not require carrier proteins to facilitate their transport. (C ) The secondary wall is capable of growth and it is formed on the outer side of the primary wall. (D) Quasifluid nature of lipid enables the lateral movement of proteins within the overall lipid bilayer of the plasma membrane. (E) Middle lamella glues the different neighbouring cells together. How many statements are incorrect?

    ......... can not pass through the lipid bilayer, they require a carrier protein of the membrane to facilitate their transport across the membrane

    ………….. can not pass through the lipid bilayer, they requist carrier protein of the membrane to facilitate their transportation across the membrane
