1.	Which of these does not take place when light falls on the photopigments of the eye?(a) Opsin undergoes conformational changes(b) Action potentials are generated in the ganglion cells(c) Retinal and opsin bind together(d) Potential differences are generated in the photoreceptor cellsI had been asked this question in an international level competition.Enquiry is from Neural Control and Coordination topic in section Neural Control and Coordination of Biology – Class 11
Answer» RIGHT option is (c) RETINAL and opsin BIND together To EXPLAIN: When light falls on the photopigments, retinal and opsin dissociate and opsin undergoes conformational changes. Potential differences are generated in the PHOTORECEPTOR cells which lead to action potentials being generated in the ganglion cells.
