WebDec 10, 2024 · Phosphate is the most abundant intracellular anion and is essential for membrane structure, energy storage, and transport in all cells. In particular, phosphate is necessary to produce ATP,... The functioning of a signal transduction pathway is based on extra-cellular signaling that in turn creates a response that causes other subsequent responses, hence creating a chain reaction, or cascade. During the course of signaling, the cell uses each response for accomplishing some kind of a purpose along the way. Insulin secretion mechanism is a common example of signal transduction pathway mechanism.

WebOct 9, 1998 · We suggest the hypothesis that insulin resistance is dependent on whether glucose is entering through GLUT1 or GLUT4 and on the two functional compartments of glucose 6-phosphate formation within the cell. Glucose entering the muscle cell through GLUT4 and phosphorylated by hexokinase II is mainly directed to glycogen synthesis and … WebThus, the insulin-mediated dephosphorylation of GS and phosphorylase involves both phosphatase activation and kinase inactivation. Insulin-stimulated glucose transport also plays a critical role in regulating GS, since removal of extracellular glucose markedly reduces the activation of GS by insulin (Brady et al., 1999a;
