After a meal a person's blood glucose rises to 180 mg/dL. Insulin secretion increases proportionally to the excess glucose above 100 mg/dL at a rate of 0.5 µU/mL per mg/dL, while glucagon secretion decreases proportionally to the same excess at a rate of 0.2 µU/mL per mg/dL. If the fasting baseline levels are insulin 10 µU/mL and glucagon 80 µU/mL, what are the new insulin and glucagon concentrations?

Answer Options

A. Insulin = 45 µU/mL; Glucagon = 68 µU/mL
B. Insulin = 60 µU/mL; Glucagon = 56 µU/mL
C. Insulin = 50 µU/mL; Glucagon = 80 µU/mL
Correct Answer D. Insulin = 50 µU/mL; Glucagon = 64 µU/mL
Correct Answer
D
Correct Option:
Insulin = 50 µU/mL; Glucagon = 64 µU/mL
