A)They proposed protein-lined pores.
B)They proposed lipid-lined pores.
C)They proposed carbohydrate-lined pores.

Quizplus · Accepted Answer

Davson and Danielli proposed protein-lined pores to account for the selective permeability of ions and polar solutes through the membrane. This allowed for the passage of these polar molecules, while still maintaining the overall hydrophobic nature of the lipid bilayer.
