Webppt = 1000 mg/L). Unlike chloride (Cl–) concentration, you can think of salinity as a measure of the total salt concentration, comprised mostly of Na+ and Cl– ions. Even though there are smaller quantities of other ions in seawater (e.g., K+, Mg2+, or SO 4 2–), sodium and chloride ions represent about 91% of all seawater ions. WebOnly the concentrations of Na+and K+are shown, because these are the ions that function in the transmission of nerve impulses. Na+is pumped out of the cell while K+is pumped in, (more...) As discussed in Chapter 10, … The Na-K-Cl cotransporter (NKCC) is a transport protein that aids in the secondary active transport of sodium, potassium, and chloride into cells. In humans there are two isoforms of this membrane transport protein, NKCC1 and NKCC2, encoded by two different genes (SLC12A2 and SLC12A1 respectively). … Meer weergeven NKCC proteins are membrane transport proteins that transport sodium (Na), potassium (K), and chloride (Cl) ions across the cell membrane.
