Which statement is false?a)Steroid hormones act by passing through the...
False Statement: Insulin is produced in the islets of Langerhans in the spleen, when blood sugar levels fall.
Explanation:
Insulin is a hormone produced by the beta cells of the islets of Langerhans, but it is not produced in the spleen. The islets of Langerhans are clusters of cells found within the pancreas, specifically in the regions called the pancreatic islets. The pancreatic islets contain different types of cells, including alpha cells that produce glucagon and beta cells that produce insulin.
Insulin plays a crucial role in regulating blood sugar levels. When blood sugar levels rise after a meal, the beta cells of the pancreas release insulin into the bloodstream. Insulin then acts on various tissues, including muscle, liver, and adipose tissue, to facilitate the uptake, utilization, and storage of glucose. This helps to lower blood sugar levels and maintain them within a normal range.
Key Points:
- Insulin is produced by the beta cells of the islets of Langerhans in the pancreas.
- The islets of Langerhans are not located in the spleen.
- Insulin is released in response to high blood sugar levels, not when blood sugar levels fall.
Therefore, option D is the false statement.
