After a meal rich in carbohydrates, which change would NOT be expected in a normal human?
A) increased secretion of the pancreatic hormone, insulin
B) increased activity of the liver enzyme, glucokinase
C) increased glucose uptake in myocytes via GLUT4 transporters
D) decreased activity of GSK-3 in both myocytes and hepatocytes
E) increased activity of glucose 6-phosphatase in hepatocytes

Question

Quizplus · Accepted Answer

After a meal rich in carbohydrates, the body works to reduce blood glucose levels. This involves increased insulin secretion, activation of glucokinase in the liver to facilitate glucose uptake, and increased glucose uptake in myocytes via GLUT4 transporters. GSK-3 activity is also decreased to promote glycogen synthesis. However, glucose 6-phosphatase activity, which is involved in glucose production, would not be expected to increase postprandially; it is more active during fasting to increase blood glucose levels.
