Question

endocrine hw
label the diagram of receptor regulation.
labels
1 high receptor density = strong response
2 reduced receptor density = reduced sensitivity
3 diminished response
4 up - regulation
5 low receptor density = weak response
drop zones
(there is a diagram with cells and receptors, and drop zones to label)

Explanation:

1. The top cell has a high number of receptors, so it has a strong response.
2. The middle cell has far fewer receptors, meaning reduced receptor density and sensitivity, leading to a diminished weak response.
3. The bottom cell shows an increase in receptor number after up-regulation, now having high receptor density again, which will produce a strong response when the ligand binds.

Answer:

Top drop zone: High receptor density = Strong response
Middle drop zone: Reduced receptor density = Reduced sensitivity; Diminished response; Low receptor density = Weak response
Bottom drop zone: High receptor density = Strong response
