Webmediated transport involving choline, K or Mg, as Na efflux is larger than Na influx in all conditions, whether in the presence or absence of choline, K, or Mg gradients. In chemistry, an ionophore (from Greek ion and -phore 'ion carrier') is a chemical species that reversibly binds ions. Many ionophores are lipid-soluble entities that transport ions across the cell membrane. Ionophores catalyze ion transport across hydrophobic membranes, such as liquid polymeric … Meer weergeven Biological activities of metal ion-binding compounds can be changed in response to the increment of the metal concentration, and based on the latter compounds can be classified as "metal ionophores", " Meer weergeven Ionophores are widely used in cell physiology experiments and biotechnology as these compounds can effectively perturb gradients of ions across biological membranes and … Meer weergeven • Fluka ionophores for ion-selective electrodes • Medical Information database Reference.MD • Structures and Properties of Naturally Occurring Polyether Antibiotics, J.
