GABA and Glycine

Question 1

Hyperpolarisation

Answer 1

A change in a cell’s membrane potential that takes it further away from 0mV.

Question 2

Glutamate decarboxylase (GAD)

Answer 2

The enzyme that mediates the conversion of glutamate to GABA

Question 3

GABA

Answer 3

A major inhibitory neurotransmitter in the CNS

Question 4

Glycine

Answer 4

Another major inhibitory neurotransmitter in the CNS

Question 5

Vesicular inhibitory amino acid transporter (VIAAT)

Answer 5

The transporter responsible for sequestering GABA and glycine into vesicles from the cytosol in the presynaptic bouton
