WebMar 28, 2024 · Normally, pancreatic beta cells regulate serum glucose levels through tight control of insulin secretion. Glucose first enters the beta cell via a GLUT2 transporter and is converted to glucose-6-phosphate via glucokinase. Glucose-6-phosphate acts as the initial substrate for the complex metabolic and biochemical processes that produce ATP. WebThe insulin transduction pathway is a biochemical pathway by which insulin increases the uptake of glucose into fat and muscle cells and reduces the synthesis of glucose in the liver and hence is involved in maintaining glucose homeostasis. This pathway is also influenced by fed versus fasting states, stress levels, and a variety of other hormones.
