Explanation

Insulin is produced by the pancreas, which is an organ located behind the stomach.

The pancreas contains clusters of cells called the Islets of Langerhans, specifically the beta cells within these islets, which are responsible for producing insulin.

Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production or storage.

When blood sugar levels rise after a meal, the pancreas releases insulin to help lower blood sugar levels by promoting the uptake of glucose into cells.

Explanation

• Human insulin is inserted into bacteria, specifically E. coli, for the commercial preparation of insulin.
• This is done through genetic engineering, where the human insulin gene is cloned into a plasmid and then transformed into E. coli cells.
• The bacteria then produce human insulin, which can be harvested and used as a medication for diabetes.
