Question

Quizplus · Accepted Answer

Glucagon primarily acts on hepatocytes to stimulate glycogenolysis and gluconeogenesis, which increases blood glucose levels. While glucagon is also secreted by pancreatic alpha cells, these cells are not considered target cells for glucagon. Glucagon has no significant effect on intestinal epithelium cells.
