How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not, then how are these transported across the membrane? | NCERT solution | Class 11 Biology | Unit-8 The Unit of Life



Q.6:- How do neutral solutes move across the plasma membrane? Can the polar molecules also move across it in the same way? If not, then how are these transported across the membrane?

 

Answer



Neutral solutes move across the plasma membrane through osmosis. On the other hand polar molecules cannot pass through the non-polar membrane. They require a carrier protein to help them transverse across the membrane. Such a transport requires energy and is called active transport.
