Answer to Question 1

Correct Answer: 1
Rationale: Parkinson's disease results in the death of neurons that produce dopamine. Due to the imbalance, dopamine is provided (levodopa), and anticholinergics can be administered as well.

Answer to Question 2

Correct Answer: 1
Rationale: Levodopa can cross the bloodbrain barrier, where dopamine cannot. Levodopa administration leads directly to dopamine synthesis.
