Which hormone helps to increase blood glucose to maintain homeostasis?
Calcitonin
Insulin
Glucagon
Parathyroid hormone
The Correct Answer is C
Choice A rationale
Calcitonin is a hormone produced by the thyroid gland. Its primary function is to regulate calcium levels in the body, not blood glucose.
Choice B rationale
Insulin is a hormone produced by the pancreas. It allows cells in the body to take in glucose and use it for energy. However, insulin actually lowers blood glucose levels rather than increasing them.
Choice C rationale
Glucagon is a hormone also produced by the pancreas. It works to raise blood glucose levels by stimulating the liver to convert stored glycogen into glucose, which is then released into the bloodstream.
Choice D rationale
Parathyroid hormone is produced by the parathyroid glands. Its main role is to control calcium levels in the body, not to regulate blood glucose.
