A protein is a large sequence of amino acid that was translated in ribosomes (or rough endoplasmic reticulum) from a mRNA that was transcribed in the nucleus from DNA.
If the protein has an extracellular function (like immunoglobulin) if should be
exocytosed from the cell.
The protein in the cell is driven to the membrane into
vesicles that have
a specific receptor, which allows, while in contact with the inner side of the cell membrane to open it and let the protein being transported in the extracellular medium.
Pollution caused the environment to become more darkly colored, so moths were selected to be blacks and greys. Before pollution they were white and lighter colors. <span />

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
and
. Even glycine transporters are also members of the large family of
dependent neurotransmitter transporters. Both of them with the GABA transporters share approximately 50% sequence identity.
