Which of the following substances can easily pass
directly through the lipid portion of the bilayer
unassisted? Select all that apply!
a. ions
b. water
c. steroid hormones
d. gases
e. large biomolecules
Steroid hormones can pass through lipid portion of bilayer because steroids are lipids and they don't repel each other so they can easily slip inside.
Lipid bilayer allows smaller particles to pass through them,so the gases like O2 and C02 can easily pass.
So steroid hormones and gases can easily pass through the lipid portion of the bilayer unassisted.
