Explanation:

To determine the neurotransmitter involved in movement regulation and affected in Parkinson’s disease, we analyze each option:

• Serotonin: Regulates mood, sleep, etc., not movement/Parkinson’s.
• Dopamine: Critical for motor control; Parkinson’s involves dopamine - producing neuron loss.
• Glutamate: Excitatory neurotransmitter, not primary for movement/Parkinson’s.
• Norepinephrine: Regulates stress, arousal, not movement/Parkinson’s.

Answer:

B. Dopamine
