WebGlucokinase: liver and β-cells of the pancreas have a lower affinity for glucose than hexokinases of other tissues Low glycemia (portal blood): Glucose is available to extrahepatic tissue. High glycemia (portal blood): Glucose enters the liver and is stored as glycogen. PFK-1 Pyruvate kinase PFK-1 and hexokinase / glucokinase require ATP.

WebHK2. Hexokinase 2 also known as HK2 is an enzyme which in humans is encoded by the HK2 gene on chromosome 2. [5] [6] Hexokinases phosphorylate glucose to produce glucose-6-phosphate (G6P), the first step in most glucose metabolism pathways. This gene encodes hexokinase 2, the predominant form found in skeletal muscle. WebHexokinase is the most widely distributed isoform. Its low K m allows glucose to enter cells, especially brain cells and RBCs, under fasting conditions. Excess removal of glucose …
