Question

Carbohydrate metabolism is controlled by

• A. Parathormone
• B. Insulin
• C. Glucose
• D. Vitamin B${}_{12}$

Answer 1

Answer: (B)

Insulin

Insulin is a peptide hormone produced by the pancreas in animals including humans. Insulin decreases blood glucose level. On the other hand, another pancreatic hormone glucagon serves to increase blood glucose level. Thus, a constant level of blood glucose is maintained by the balance between these two hormones. Immediately after a meal, insulin is secreted and it increases carbohydrate or sugar metabolism while in between meals glucagon is secreted and it increases blood glucose level.

So, the correct answer is option B.
