Concept explainers
(a)
Interpretation:
Define term synapse.
Concept Introduction:
The neurons are the cells, which are responsible for the transfer of the signals from the body to.
brain and vice-versa. These nerves are arranged in different pathways, which carry a message from.
different regions of the body. The gap between two neuron at its junction is synapse.
(b)
Interpretation:
Define term receptor.
Concept Introduction:
The cells are enclosed in a semipermeable cell membrane. This membrane does not allow the entry of the molecules inside it. Hence, the cell membrane posses many receptors, where the ligands can bind to generate a cellular response.
(c)
Interpretation:
Define the term presynaptic.
Concept Introduction:
The neurons are the cells, which are responsible for the transfer of the signals from the body to.
brain and vice-versa. These nerves are arranged in different pathways, which carry a message from.
different regions of the body. The gap between two neuron at its junction is synapse.
(d)
Interpretation:
Define term postsynaptic.
Concept Introduction:
The neurons are the cells, which are responsible for the transfer of the signals from the body to.
brain and vice-versa. These nerves are arranged in different pathways, which carry a message from.
different regions of the body. The gap between two neuron at its junction is synapse.
(e)
Interpretation:
Define term vesicles.
Concept Introduction:
The exocytosis is a process, by which a cell sends a chemical capable of eliciting a response in a membrane-bound vesicle. The endocytosis is a process, by which a cell uptake a membrane-bound vesicle.

- These two reactions appear to start with the same starting materials but result in different products. How do the chemicals know which product to form? Are both products formed, or is there some information missing that will direct them a particular way?arrow_forwardWhat would be the best choices for the missing reagents 1 and 3 in this synthesis? 1. PPh3 3 1 2 2. n-BuLi • Draw the missing reagents in the drawing area below. You can draw them in any arrangement you like. • Do not draw the missing reagent 2. If you draw 1 correctly, we'll know what it is. • Note: if one of your reagents needs to contain a halogen, use bromine.
