Aperson with type i diabetes cannot make insulin in the pancreas, and a person with untreated type ii diabetes does not respond to the insulin that is made in the pancreas. in either case, why would you expect to find glucose in theperson's urine

Insulin is a substance with the function of, apart from many other things, regulating the glucose levels in the blood. When sugar levels are low, the liver is responsible for secreting glucose into the blood. When sugar levels are high, insulin is secreted into to blood, in order to lower the sugar levels.

If in both types of diabetes insulin isn't managing to do it's job, it is absolutely logical to find glucose in the person's urine since it wasn't metabolised nor regulated.

Hope it helped,

Happy homework/ study/ exam!
