1. Which hormone, produced by the pancreas, is released in response to low blood sugar levels and stimulates the release of glucose into the bloodstream?

A. Insulin
B. Glucagon
C. Cortisol
D. Thyroxine

Correct answer: b

Rationale: The correct answer is B: Glucagon. Glucagon is a hormone produced by the pancreas that is released in response to low blood sugar levels, also known as hypoglycemia. When blood sugar levels drop, glucagon acts to stimulate the liver to release stored glucose into the bloodstream, helping to raise blood sugar levels back to a normal range. Insulin, on the other hand, is released in response to high blood sugar levels and helps to lower blood sugar by promoting the uptake of glucose by cells. Cortisol is a stress hormone produced by the adrenal glands, and thyroxine is a hormone produced by the thyroid gland that regulates metabolism. Therefore, glucagon is the hormone specifically responsible for stimulating the release of glucose into the bloodstream in response to low blood sugar levels.
