Question
Chapter 34, Problem 10P
Interpretation Introduction
Interpretation:
The effect of light absorption on 11-cis-retinal bound within the rhodopsin should be determined.
Concept introduction:
The photoreceptors are the cells involved in the sensation of the light. The photoreceptor cells present in the eyes are rods and cones. The cones are the cells involved in the detection of the color. The rhodopsin is the sensory protein that convertsthe light signal into chemical signals.

Dear Expert.
Thank you for your advice, which is good and helpful. I note that your answer is "when 3 binding sites have been occupied the activity of these receptors is maximum."
However, I also note that for a similar question (see below) on α7 nicotinic Acetylcholine Receptor (nAChR) also gives the same answer, ie. at least 3 agonist binding sites should be occupied.
Another Question - "To maximize the activity of an α7 nAChR, how many agonist binding sites should be occupied."
I understand that in α7 nAChR, binding to two sites is more effective and binding to three sites is most effective for activation. On the other hand, binding to four or five sites in the nAChRs of chromosome 7 speeds up desensitization more than activation.
Therefore, to maximize the activity of an α7 nicotinic Acetylcholine Receptor (nAChR) is also "3 sites".
Am I right?
