K+: potassium cation, (positively-charged) potassium ion.
К42, 42К: one of the radioactive potassium isotopes with a half-life of 12.4 hours, emitting two
β-particles of 3.6 and 2.4 MEV respectively and also
γ-radiation of 1.5 MEV.
Kooi–>j: See intrinsic equilibrium constant, also known as close-contact adsorption exchange constant when i and j refer respectively to
Na+ and K+ specifically.
KooNa––>K: close-contact adsorption exchange constant of
Na+ and K+.
K-channel: hypothetical narrow pores in the nerve and muscle cell membranes that are selectively permeable to the smaller (hydrated)
K+ but not the larger (hydrated) Na+ Both the narrow K-channels and wider Na-channels (permeable only to the larger hydrated
Na+ are closed when the cells are at rest but open momentarily and sequentially during activity.
K42-labeled K+: If there are many grey-colored carps in two adjoining ponds, it is not easy to tell accurately how fast they are traveling between the two ponds. The task would be made easier if at a certain time we introduce a number of gold-colored carps into one pond and count the number of gold carps in the other pond at different times after the initial release.
K42-labeled K+ are employed just like the gold-colored carps to monitor the rate of exchange of
K+ in two pools of this ion, one inside a living cell and another outside.
K+-sensitive microelectrode: a device with a sharp tip which possesses specific sensitivity to
K+, and can penetrate into the interior of a living cell to monitor the activity of this ion in the thin layer of fluid that collects around the sensitive tip of the microelectrode (See Fig. 11 and text for more details.)
K+ surrogate: a cation which can serve as a substitute for
K+.
Kelzan: a commercially available bacterial polysaccharide of large molecular weight.
KI: potassium iodide, colorless or white cubic crystals soluble in water.
kidney epithelial cells: epithelial cells lining the renal tubules in kidneys.
kinetic: of or relating to the motion of material bodies and the forces and energy associated therewith.
kinetic energy: the energy possessed by a body due to its motion, given by the formula: K.E. = 1/2
mv2, where m is the mass of the body and v its velocity.
