How it works and why it’s important!

2. Background info.
When we eat, our bodies break food down into organic compounds, one of which is glucose.
The cells of our bodies use glucose as a source of energy for movement, growth, repair, and other functions.
Before the cells can use glucose, it must move from the bloodstream into the individual cells.
This process requires insulin.

3. Insulin
Insulin is produced by the beta cells in the islets of Langerhans in the pancreas.

4. Insulin
When glucose enters our blood, the pancreas should automatically produce the right amount of insulin to move glucose into our cells.
Insulin binds to a receptor on the surface of the cell.
This allows channels to open in the cell membrane and glucose can come in.

5. Importance People with type 1 diabetes produce no insulin.
People with type 2 diabetes still make insulin, but their cells are resistant to it.
Either way, their cells cannot take in the glucose they need.
Severe consequences may result!
