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).
Hormonal Regulation of Hormone Release. Hormonal regulation of hormone release involves a hormone binding to its receptor on an endocrine cell to regulate hormonal secretion. A hormone that stimulates hormone secretion is called a tropic hormone. Tropic hormones may also stimulate proliferation of endocrine cells.or polar hormones, tropic hormones stimulate endocrine secretion by stimulating cell secretion; that is, exocytosis. An example is the regulation of growth hormone (GH) secretion by the tropic hormone growth hormone releasing hormone (GHRH) . GHRH is a hypophysiotropic hormone.
