Explanation:

These were developed by Phoebus Aaron Theodor Levene ,he was a russian who studied medicine, with keen interest in organic chemistry.

He migrated to the US in 1891, and started practising medicine  in 1892.Due to his strong interest in research he combined research(1894) in  molecular structure of sugars with medical practice,But this was cut short when he contracted tuberculosis.

Between 1896- 1906,he collaborated with many nucleic acids  and protein exoperts  e.g Albrecht Kossel and Emil Fischer to  wok on the structure of DNA.And headed the Rockefeller Institute for Medical Research.

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing what?
Mashutka [201]

Inhibitory neurotransmitters such as glycine and GABA make a postsynaptic cell harder to depolarize by allowing "an influx of Cl-".

<u>Explanation:</u>

The neurotransmitters which have inhibitory influence on the neuron are termed as "Inhibitory neurotransmitters". The major inhibitory neurotransmitters involve serotonin and gamma-aminobutyric acid (GABA) in the brain and brain stem (spinal cord) respectively.

GABA uptake is temperature and ion-dependent as require both N a^{+} and C l^{-}. Even glycine transporters are also members of the large family of N a^{+} / C l^{-} dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.
