Answer
L-dopa is a precursor to the neurotransmitters dopamine, norepinephrine, and epinephrine, which increases their synthesis in the brain.
Solution
a
Precursor to Dopamine: L-dopa serves as a direct precursor to the neurotransmitter dopamine
b
Crosses Blood-Brain Barrier: Unlike dopamine, L-dopa can cross the blood-brain barrier where it is then converted to dopamine
c
Increases Transmitter Synthesis: By increasing the availability of L-dopa in the brain, the synthesis of dopamine is increased, which can compensate for the loss of dopamine-producing neurons in conditions such as Parkinson's disease
Key Concept
L-dopa as a precursor to neurotransmitters
Explanation
L-dopa is used to increase the levels of certain neurotransmitters in the brain by serving as a precursor that can cross the blood-brain barrier and be converted into active neurotransmitters.
