Chapter 13 - Ion permeation and membrane potential
WebBecause of the importance of ion transport across membranes (such as in action potentials), the question of the similarities of the intrinsic ion permeability and conductance has … Web4 mrt. 2024 · Here, we assemble micron-length DNA nanotubes and assess their performance as pipes for controlled ion transport. DNA nanotubes grow via assembly of DNA tiles from a seed pore, a 12-helix DNA origami cylinder functionalized with cholesterol, to form a DNA nanotube channel. The central channel of a nanotube can be obstructed … WebSeveral things dictate how permeable the membrane is to a substance, such as the substances size (is it small enough to easily pass between the phospholipid bilayer- e.g. water), or is it lipid-soluble (as the membrane consists of lipids, they will often resist larger molecules that are lipid-insoluble). permeability to Ions as in this lesson is … great clips menomonie wi
