State
Insulin, released as blood glucose rises, lowers it by promoting cellular uptake and glycogen storage; glucagon, released as glucose falls, raises it by promoting glycogen breakdown — maintaining homeostasis.
Show
Insulin resistance or insufficient insulin causes glucose to accumulate in blood rather than entering cells, defining diabetes mellitus.
Watch for
Some cells, including kidney and brain cells, can access glucose without insulin, unlike most tissue.
