Compared to glycerol (shown), O2 has a higher rate ofpassive permeability through a cell membrane. Which of thesecorrectly explains why? Choose all that apply.
a. The most energetically challenging part of traversing amembrane is passing through the hydrophobic interior. Hydrophobicmolecules can more easily do this and so can pass through membranesmore easily.
b. The most energetically challenging part of traversing amembrane is passing through the polar head groups. Polar moleculescan more easily do this and so can pass through membranes moreeasily.
c. Being composed of two identical atoms, electrons are sharedequally within O2, making it non-polar, while glycerolis polar.
d. Glycerol is more hydrophobic than O2, whichcontains highly electronegative atoms.
e. O2 is smaller than glycerol
