Question

Glutamate is not:

A. One of the two major amino acid neurotransmitters
B. An inhibitory neurotransmitter
C. Involved in learning and memory
D. The primary neurotransmitter in cerebellar granule cells
E. A precursor of GABA

Answer 1

Glutamate is not an inhibitory neurotransmitter but the main excitatory neurotransmitter in the CNS, essential for learning and memory, and a precursor of GABA.

Step-by-step explanation:

Glutamate is not an inhibitory neurotransmitter; it is, in fact, the main excitatory neurotransmitter in the central nervous system (CNS). Glutamate plays a critical role in learning and memory and is the primary neurotransmitter in cerebellar granule cells. Additionally, glutamate serves as a precursor of the inhibitory neurotransmitter GABA (gamma-aminobutyric acid).
