If a drug inhibits pancreatic beta cell glucokinase in a patient with Type 2 diabetes already exhibiting insulin resistance, which consequence follows?

A)Enhanced insulin secretion efficacy
B)Reduced glucose-stimulated insulin secretion
C)Increased GLUT4 translocation in adipocytes
D)Decreased hepatic glucose production rate

💡 Explanation

Inhibiting glucokinase impairs the initial step of glucose metabolism in pancreatic beta cells, because this reduces ATP production which triggers insulin release. Therefore, glucose-stimulated insulin secretion decreases, rather than increases, while GLUT4 translocation and hepatic glucose production are not directly stimulated.
