||P.15819 right column bottom paragraph: "For CO2 to permeate by means of a membrane protein is not
unreasonable and has been suggested before (refs 15, 24). The
human red cell membrane is at least 50% protein (primary source). CO2
would have to pass through a channel or pore rather than by
a saturating process, which would be too slow." See Skotland et al., 2017 PMID 28342835 p.38 left column 5th paragraph: "As the plasma membrane of most cells has been estimated to contain approximately 50% of proteins [ref 88 Dupuy & Engelman 2008 PMID 18287056 DOI: 10.1073/pnas.0712379105],..."
