The brain also requires NA, K ATPase activity. Sperm needs the Na, K ATPase to regulate membrane potential and ions, which is necessary for sperm motility and the sperm’s acrosome functioning during penetration into the egg. Sperm cells also use the Na, K-ATPase, but they use a different isoform necessary for preserving fertility in males. This sodium gradient is necessary for the kidney to filter waste products in the blood, reabsorb amino acids, reabsorb glucose, regulate electrolyte levels in the blood, and to maintain pH. The kidneys have a high level of expression of the Na, K-ATPase, with the distal convoluted tubule expressing up to 50 million pumps per cell. Sodium and potassium gradients function in various organ systems' physiologic processes. Na, K-ATPase is a crucial scaffolding protein that can interact with signaling proteins such as protein kinase C (PKC) and phosphoinositide 3-kinase (PI3K). Furthermore, the physiologic consequences of inhibiting the Na+-K+ ATPase are useful and the target in many pharmacologic applications. It plays a crucial role on other physiological processes, such as maintenance of filtering waste products in the nephrons (kidneys), sperm motility, and production of the neuronal action potential. The sustained concentration gradient is crucial for physiological processes in many organs and has an ongoing role in stabilizing the resting membrane potential of the cell, regulating the cell volume, and cell signal transduction. The sodium and potassium move against the concentration gradients. The Na+ K+-ATPase pump maintains the gradient of a higher concentration of sodium extracellularly and a higher level of potassium intracellularly. The Na+K+-ATPase pump helps to maintain osmotic equilibrium and membrane potential in cells. The plasma membrane is a lipid bilayer that arranged asymmetrically, containing cholesterol, phospholipids, glycolipids, sphingolipid, and proteins within the membrane. The Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ that into the cell, for every single ATP consumed.

Create a bootable USB stick with WinPE and Microsoft Safety Scanner ^
For older Windows versions, you can use ISO recorder. In Windows 7, you can then just right-click img.iso and burn the ISO image to a CD or DVD.
I assume that you already downloaded and installed the WAIK for Windows 7 and the Microsoft Safety Scanner. Of course, you can also create a boot CD with Windows PE and Microsoft Safety Scanner. The advantage of the Windows PE solution is that you can add Microsoft Safety Scanner to your Windows administration toolbox on your USB stick.
Many antivirus software vendors offer boot kits with their scan engines, which are usually based on Linux. Windows PE is a good choice for an offline antivirus scan because the operating system is lightweight and boots up quickly. Sophisticated viruses are difficult, and sometimes impossible to remove while Windows is running and the best way to remove them is to access the infected drive from a second OS while Windows is offline.
The fact that the Microsoft Safety Scanner runs on Windows PE makes the free antivirus tool much more useful because it allows you to scan a Windows installation while it is offline. Microsoft Safety Scanner as offline antivirus tool on Windows PE 3.0
