The following steps occur in rods when they are excited by photons of light. 1.Ganglia cells detect changes in bipolar cell activity.
2)Neurotransmitter release changes.
3)Retinal changes to a more linear form.
4)Rhodopsin breaks down (bleaches).
5)Opsin changes the membrane permeability of the outer segment to Na+.
6)Opsin activation occurs.
What is the proper sequence for these steps?

Question

Quizplus · Accepted Answer

The correct sequence starts with the retinal changing to a more linear form (3), followed by opsin activation (6), which then changes the membrane permeability to Na+ (5), leading to changes in neurotransmitter release (2), which is detected by ganglion cells (1), and finally, rhodopsin breaks down (4).
