Facilitated diffusion as a method for selective accumulation of materials from the primordial oceans by a
Origins of Life
|September 1, 1980
Abstract:
A model is proposed for the selective accumulation of amino acids, sugars, nucleotides, cations and protons from the primordial oceans into a lipid vesicle type of protocell. The model is built on facilitated diffusion using simple, primordial, lipid-soluble carriers. The advantages a lipid vesicle protocell would have had over the other potential types of protocells are discussed.
