Which of the following statements about hormones is not correct?

Insulin hormone regulates blood sugar and is secreted by pituitary gland

The correct answer is (4) Insulin hormone regulates blood sugar and is secreted by the pituitary gland.

The given statement is: "Insulin hormone regulates blood sugar and is secreted by the pituitary gland."

1. Insulin hormone regulates blood sugar:
Insulin is a hormone produced by the beta cells of the pancreas. Its primary role is to regulate blood sugar (glucose) levels in the body. When you consume food, especially carbohydrates, the body breaks down these carbohydrates into glucose, which enters the bloodstream. Insulin facilitates the uptake of glucose by cells, allowing them to use it for energy or store it for future use.

2. Is secreted by the pituitary gland:
This part of the statement is incorrect. The pituitary gland does secrete hormones, but insulin is not one of them. The pancreas is the organ responsible for producing and releasing insulin. The pancreas is located behind the stomach and has both endocrine and exocrine functions. The endocrine function involves the release of hormones like insulin directly into the bloodstream.

Therefore, the corrected statement should be: "Insulin hormone regulates blood sugar and is secreted by the pancreas."

To summarize, insulin is a crucial hormone for maintaining blood sugar levels, but its production and secretion occur in the pancreas, not the pituitary gland.
