Parker Sullivan · Accepted Answer

Final Answer : A, Explanation :  Parkinson's disease is caused by a deficiency of dopamine in the brain. L-DOPA is a precursor to dopamine and can be converted into dopamine in the brain. Therefore, taking pills that contain L-DOPA can help alleviate the symptoms of Parkinson's disease. MPTP, on the other hand, can actually cause Parkinson's-like symptoms and is not a treatment for the disease. Epinephrine is not effective in treating Parkinson's disease as it does not have the same mechanism of action as dopamine. Finally, dopamine itself cannot be taken orally as it is not able to cross the blood-brain barrier.

Parkinson's disease can be helped by

A) taking pills that contain L-DOPA.
B) taking pills that contain MPTP.
C) injections of epinephrine.
D) taking pills that contain dopamine.
