Insulin controls: 

The correct answer is 'Level of sugar in the blood'

Key Points

• Insulin and Blood Sugar Levels:
  • Insulin is a hormone produced by the pancreas that plays a crucial role in regulating blood sugar (glucose) levels.
  • When you eat, carbohydrates are broken down into glucose, which enters the bloodstream. Insulin helps cells absorb glucose to be used for energy or stored for future use.
  • If the body does not produce enough insulin or if cells become resistant to insulin, blood sugar levels can become elevated, leading to conditions like diabetes.

Additional Information

• Iodine level in the thyroid:
  • Iodine is essential for the production of thyroid hormones, which regulate metabolism, but insulin does not control iodine levels.
• Amount of iron in the blood:
  • Iron levels are regulated by dietary intake, absorption, and storage, primarily involving the liver and bone marrow, not insulin.
• Level of urea in the blood:
  • Urea levels are regulated by the liver and kidneys, as urea is a waste product from protein metabolism, not directly influenced by insulin.
