Webb- allow water molecules and small ions to flow quickly across the membrane only channels Sort the phrases into the appropriate bins depending on whether they are true only for channels, true only for carrier proteins, or true for both channels and carriers. - provide a continuous path across the membrane only channels Webb31 aug. 1998 · One can thus argue that the source of small ions in electrospray ionization is field‐emission, and not other proposed mechanisms such as Dole’s charged residue model. A consequence of the observed independence of E on d r is that the rate of ion ejection is simply related to the rate of solvent evaporation, estimated here as that for a …

Webb2 dec. 2024 · Small ions and molecules can move through a gel or liquid much more quickly than larger ones. While a charged particle is attracted to an opposite charge in an electric field, there are other forces that affect how a molecule moves. Friction and the electrostatic retardation force slow the progress of particles through the fluid or gel. WebbSmall ions in biological fluids: A) encourage strong electrostatic interactions between oppositely charged macroions at low ionic strengths. B) encourage strong electrostatic interactions between oppositely charged macroions at high ionic strengths. C) have no effect on the interactions between oppositely charged macroions.
