Diabetes

          Type 1

• Developed in childhood.
• Insulin not produced so blood glucose levels remain high.
• May be genetic.
• Controlled by injecting insulin.

        Type 2

• Developes in older people.
• Insulin produced but liver cells do not respond, so glucose is not converted into glycogen so blood glucose levels remain high.
• Caused by obesity (overweight) and/or lack of exercise.
• Can be controlled by diet.

• Glucose is converted/changed into glycogen.
• Increased rate of respiration of glucose.

  (glucose + oxygen → carbon dioxide +water +Energy)

• Increased up take of glucose by cells.
• Glucose is converted/changed to fat.

★If you are asked, 'How does the liver respond to insulin?', give the above points.

Why can insulin not be swallowed and instead has to be injected?Insulin is a protien and would be broken down by protease in the stomach.
