Sodium transport mechanismsLithiumCarbamazepineStressful life events can be triggering factor for the development of the disease, and worsening suffering. The study included 62 patients with schizophrenia, 41- with bipolar disorder, and 34 healthy controls. Life events were evaluated with Social Re...
aTo maintain the balance of sodium and potassium, all cell membranes incorporate sodium-potassium pumps that actively pump sodium out of the cell while allowing potassium back in. 要维护钠和钾平衡,所有细胞膜合并活跃地抽钠在细胞外面,当允许钾后面in.时的sodium-potassium泵浦。[translate]...
- Active transport: movement of molecules from low concentration to high concentration; - Example: Na+ and K+ are transported against their concentration gradients by a sodium-potassium pump. Na⁺/K⁺-ATPase (sodium–potassium adenosine triphosphatase, also known as the Na⁺/K⁺ pump or s...
Figure 5. Renal transport of sodium. K+, potassium ion; H+, hydrogen ion; Na+, sodium ion; Na+–K+–ATPase pump, sodium–potassium–adenosine triphosphatase pump. The sodium exchanger moves Na+ into the cell in exchange for another cation (e.g., K+ and H+), sodium cotransporter coupl...

For example, we find the catalytic α-subunit of Na+-K+ pump, which maintains cytoplasmic high potassium and low sodium, from bacteria to vertebrates. In addition, its β-subunit, which promotes cell adhesion, we find in basal metazoans, such as choanoflagellates and the placozoan Trichoplax...
be very different. One group involves carrierswhich need several steps of structural changes for the transport. Some carriers are powered externally (i.e., by dephosphorylation of ATP) and can facilitate transport against the electrochemical gradient (i.e., NA/K ATPase, sodium–potassium pump). ...
