C) "Stored glycogen is broken down by ephedrine, which is causing higher blood sugar levels."
D) "Insulin is inactivated by ephedrine so it cannot work to control sugar levels."

Ephedrine breaks down stored glycogen, which then enters the bloodstream as glucose and causes an increase in serum blood glucose, or blood sugar, levels. Ephedrine is not mixed with sugar and is not a placebo. Ephedrine has no effect on insulin.
