42. Passage through a cell membrane
A) occurs through the lipids
B) only occurs through phosphates
C) does not occur at all
D) A and C
E) None of the above
Homework Answers
Option a, occurs through lipid
Cell membrane are made up of lipis ( phospholipids) as main components. Non polar molecules can easily cross the cell membrane by process of simple diffusion.
Option B is wrong, charged molecule of membrane dl not allow transport of molecules
Option c is wrong, membrane involve in transport of molecules.
