Abstract
We describe possible pathways for separating amphiphilic molecules from organic material on the early earth to form membrane-bound structures required for the start of cellular life. We review properties of the first membranes and their function as permeability barriers. Finally, we discuss the emergence of protein-mediated ion transport across membranes, which facilitated many other cellular functions.
