Glucagon, a hormone produced by the pancreas, generally has what specific effect on blood sugar levels, working in a complementary way alongside insulin?

Explanation

Glucagon is a hormone produced by the pancreas that generally works to raise blood sugar levels, primarily by signaling the liver to break down its stored reserves of glycogen and release the resulting glucose into the bloodstream, helping to counteract low blood sugar levels. This action works in a complementary, opposing way alongside insulin, another pancreatic hormone that instead helps lower blood sugar levels by facilitating glucose uptake into cells. Together, this balanced interplay between glucagon and insulin helps the body maintain relatively stable blood sugar levels despite the ongoing variations in food intake and physical activity throughout a typical day.
