An oral glucose load is cleared from the circulation more rapidly compared with an intravenous glucose load. This interesting phenomenon can be attributed to the actions of which hormone?
A)Cholecystokinin
B)Gastrin
C)Glucose-dependent insulinotropic peptide
D)Motilin
E)Secretin

Question

Quizplus · Accepted Answer

Glucose-dependent insulinotropic peptide (GIP), released by the small intestine in response to oral glucose intake, stimulates insulin secretion from pancreatic beta cells. This increases glucose uptake by tissues and speeds up the clearance of glucose from circulation. Intravenous glucose administration bypasses this pathway and therefore takes longer to clear from circulation.
