Question

Lack of causes Diabetes

1. A. Sugar
2. B. Insulin (Correct answer)
3. C. Calcium
4. D. Vitamins

Correct Answer

Option B — Insulin

Detailed Solution & Explanation

The correct answer is Insulin.

Key Points

• Diabetes mellitus results from a lack of insulin, or from the body's inability to use it effectively.
• Insulin is a hormone secreted by the beta cells of the islets of Langerhans in the pancreas, and it lowers blood glucose by helping cells absorb it.
• Without enough insulin, glucose accumulates in the blood — hyperglycaemia.

Additional Information

• Type 1 diabetes is an autoimmune condition in which the beta cells are destroyed, so insulin is absent; Type 2, far more common, involves insulin resistance.
• Glucagon, from the alpha cells of the same islets, has the opposite effect, raising blood glucose — the two hormones are antagonistic.
• Insulin was isolated by Banting and Best in 1921. World Diabetes Day is 14 November, Banting's birthday.
