Answer:
D
Explanation:
This is because one of its orbital shells is not filled – the one with 1 electron. This atom will, therefore, want to lose this electron – it takes less energy to do this than gain 7 electrons -- to achieve stable electron configuration. This makes this atom very reactive in a chemical reaction. Usually orbital shells of atoms begin with an S orbital shell that is filled with 2 electrons then P (x,y,z) orbital shells filled with 6 electrons total. There are also higher energy f and d orbitals that each take a maximum 10 and 14 electrons respectively. An atom is stable if its orbitals are fully filled.

Answer:
Explanation:
TransA can be found in the plasma membrane, while TransB is found in the cytoplasm, according to the immunofluorescence localization test analysis. There are two main varieties of serotonin transporters in the neural system when it comes to serotonin signaling.
- An intracellular transporter that carries and delivers serotonin throughout synaptic vesicles.
- A transmembrane transporter that prevents hyperactivity overstimulation by re-uptaking serotonin from the synapse.
Therefore, suppose we compare this signaling pathway model to the analyzed experimental test. We can vividly acknowledge that TransA acts as a serotonin reuptake transporter since it is present in the plasma membrane of nerve cells and TransB is a serotonin vesicle transporter that is present and located in the cytoplasm. As a result, the majority of TransB is speculated to be present in synaptic vesicle membranes.
