A scientist places muscle cells from a person with type 2 diabetes in a glucose solution and then adds insulin. The scientist repeats this with the same number of muscle cells from a person who does not have diabetes.
Which observation is most likely for the muscle cells from the person with type 2 diabetes?
the glucose concentration of the solution decreases more quickly than with the cells from the person without diabetes
the glucose concentration of the solution decreases at the same rate as with the cells from the person without diabetes, because insulin has been added
the muscle cells convert stored glycogen into glucose and release it into the solution because insulin is present
the glucose concentration of the solution decreases more slowly than with the cells from the person without diabetes
