To facilitate glucose uptake, insulin is secreted by beta cells in islets upon glucose exposure, and insulin signaling is activated in other cells, such as muscle cells, to promote glucose uptake after glucose consumption1. Insulin signaling is initiated by the binding of insulin to the α subuni...
Produced and secreted by the beta cells of the islets (insulae) of Langerhans of the pancreas, the hormone which regulates the use and storage of foodstuffs, especially the carbohydrates. Chemically insulin is a small, simple protein. Insulins from various species differ in the composition; these...
Insulinis secreted by the pancreas. 胰岛素是胰腺分泌的。 《牛津高阶英汉双解词典》 Insulinis produced commercially from animals. 为获利从动物体内提取胰岛素。 柯林斯例句 展开全部 真题例句 全部 六级 When Liu, the UCLA sleep researcher and professor of medicine, brought chronically sleep-restricted people...
Insulin is secreted in discrete insulin secretory bursts. Regulation of insulin release is accomplished almost exclusively by modulation of insulin pulse mass, whereas the insulin pulse interval remains stable at 鈭 4 min. It has been reported that in vivo insulin pulses can be entrained to a ...
13. Then it is thought that the stagnation of spleen is the key of hyperlipidemia and insulin resistance. 湿热致病的过程中,气机失调是人体正气方面的最主要病理改变。 14. In dogs this is caused by autoimmune disease or severe pancreatitis. Type 2 diabetes, characterized by insulin resistance, is ...
insulin, hormone that regulates the level of sugar (glucose) in the blood and that is produced by the beta cells of the islets of Langerhans in the pancreas. Insulin is secreted when the level of blood glucose rises—as after a meal. When the level of blood glucose falls, secretion of ...
Insulin is a hormone secreted by pancreatic β-cells based on the availability of circulating blood glucose and fatty acids [11]. The metabolic function of insulin is to maintain the homeostasis of glucose and lipids. When we take a meal, the blood glucose level rises in circulation; pancreatic...
Insulin is a key hormone for coordinating nutrient intake with energy production and storage through both excitatory and inhibitory actions. Insulin is secreted from pancreatic β-cells with blood glucose being the main secretagogue in humans. As an anabolic hormone, insulin accelerates glucose uptake ...
27. Which of the following descriptions of insulin is not correct? A It is a protein. B It is secreted by an endocrine gland. C It is carried by the blood to the target organs. D It catalyses the conversion of glucose to glycogen. 相关知识点: 试题来源: 解析 D 反馈 收藏 ...
Moreover, IR is expressed widely in the brain. IGF2 is secreted by the choroid plexus into cerebrospinal fluid (approximately 1000 times more than insulin) and promotes stem cell self-renewal and expansion of neural progenitor cells through IR65,66,67. Therefore, it is tempting to speculate tha...
