The gigabyte (/ËÉ¡ÉªÉ¡ÉbaÉªt/ GIG-É-byt or /ËdÊÉªÉ¡ÉbaÉªt/) is a multiple of the unit byte for digital information. The prefix giga means 109 in the International System of Units (SI). Therefore, one gigabyte is 1000000000bytes. The unit symbol for the gigabyte is GB. This definition is used in all contexts of science, engineering, business, and many areas of computing, including hard drive, solid state drive, and tape capacities, as well as data transmission speeds.
The regulation of K+ distribution between the intracellular and extracellular space is referred to as internal K+ balance. The most important factors regulating this movement under normal conditions are insulin and catecholamines (1).
The key to understanding the resting potential is the fact that ions are distributed unequally on the inside and outside of cells, and that cell membranes are selectively permeable to different ions. K+ is particularly important for the resting potential. The membrane is highly permeable to K+. In addition, the inside of the cell has a high concentration of K+ ([K+]i) and the outside of the cell has a low concentration of K+ ([K+]o).
