Match List I with List II

List I	List II
A. Glutamate	I. Catecholamine
B. Dopamine	II. Amino acid
C. Acetylcholine	III. Indoleamine
D. Serotonin	IV. Quaternary amine

Correct option is D

The correct answer is (4).
1. Glutamate (A) is an amino acid neurotransmitter and corresponds with II, "Amino acid."
2. Dopamine (B) is a catecholamine neurotransmitter and corresponds with I, "Catecholamine."
3. Acetylcholine (C) is a quaternary amine neurotransmitter and corresponds with IV, "Quaternary amine."
4. Serotonin (D) is an indoleamine neurotransmitter and corresponds with III, "Indoleamine."

1. Types of Neurotransmitters and Their Functions

1.1 Glutamate:
Type: Amino acid
Role: The most abundant excitatory neurotransmitter in the brain. It plays a critical role in synaptic plasticity, learning, and memory formation. Excess glutamate is associated with neurodegenerative diseases like Alzheimer's.

1.2 Dopamine:
Type: Catecholamine
Role: Involved in reward, motivation, and motor control. It is linked to pleasure and reward circuits and plays a key role in Parkinson’s disease and addiction.

1.3 Acetylcholine:
Type: Quaternary amine
Role: A key neurotransmitter in both the central nervous system (CNS) and peripheral nervous system (PNS). It is involved in muscle movement, memory, and learning. Low levels of acetylcholine are associated with Alzheimer's disease.

1.4 Serotonin:
Type: Indoleamine
Role: Regulates mood, appetite, sleep, and pain perception. Serotonin imbalance is linked to depression, anxiety, and other mood disorders.
