Action of Insulin
|Low glucose||High glucose|
|Effect on liver||Does not convert glucose into glycogen||Converts glucose into glycogen|
|Effect on |
Insulin in the presence of high glucose causes the liver to convert glucose
into a molecule called glycogen, which is used for storage. When there is
no insulin, and there are low levels of glucose in the blood, molecule called
glycogen is converted into glucose.
When insulin does not work properly this can cause diabetes. Diabetes is a
condition where the blood glucose level remains high..There are two types
of diabetes :
Type 1 diabetes is when there is a complete lack of insulin. The insulin is
not produced in the body, this is usually due to a genetic defect from birth
Type 2 diabetes is when there is plenty of insulin but it is not working properly,
as the person has become resistant to it.
