Unformatted text preview: amino acid to growing polypeptide chain 19 See book. Protein is helical where passing through membrane and is by hydrophobic interactions between amino acid sidechains and tails of phospholipids. 20 Plot rate of diffusion as a function of conc. Passive diffusion gives a linear relationship, but facilitated diffusion a hyperbolic relationship due to saturation of membrane carrier proteins at high substrate concs. 21 Ala-Val-Lys-Ala-Tyr-Arg...
