Question

What does glucagon do to blood sugar?

Answer 1

Glucagon:

1. Glucagon is a hyperglycemic hormone which is secreted by the pancreas.
2. Pancreas secrete glucagon 4-6 hours after food is eaten.
3. This is because when food is eaten, glucose level in blood decreases and the pancreas are triggered to secrete glucagon.
4. Glucagon signals liver and muscle cells to convert stored glucagon into glucose.

Glucagon to blood sugar:

1. Glucagon increases blood sugar levels by stimulating glycogenolysis and gluconeogenesis.
2. Glucagon prevents the blood sugar level from dropping very low.
3. Glucagon decreases the uptake and utilization of cellular glucose.
