Final answer:
Insulins that have a peak include insulin in normal persons and insulin responsive diabetes mellitus (IDDM) persons, while the insulin that does not have a peak is observed in insulin non-responsive diabetes mellitus patients.
Step-by-step explanation:
The insulins that have a peak are the ones that cause a decrease in blood glucose levels followed by an increase, and then return to normal. This can be seen in Graph-A where the injection of insulin in normal persons or insulin responsive diabetes mellitus (IDDM) persons leads to a fall in blood glucose levels in one hour, followed by an increase and then returning back to normal in 2½ hours.
On the other hand, the insulin that does not have a peak is observed in insulin non-responsive diabetes mellitus patients where there is either no decrease in blood glucose levels or only a marginal decrease upon injection of insulin, as shown in Graph-B.
The insulins that have a peak:
- Insulin in normal persons
- Insulin in insulin responsive diabetes mellitus (IDDM) persons
The insulin that does not have a peak:
- Insulin in insulin non-responsive diabetes mellitus patients
