There are two types of diabetes mellitus, both of which result in a decreased
reuptake of glucose from blood. Researchers completed an investigation
comparing blood levels and receptor characteristics in tissue taken from
patients with type 1 and type 2 diabetes. Based on the results shown below,
which of the following statements most accurately describes the difference
in the underlying mechanism in these two types of diabetes mellitus?
