    Following are the steps of mechanism of vision in random order

    I. Neural impulses are analysed and image formed on retina is recognised by visual cortex

    II. Membrane permeability changes

    III. Ganglion cells are excited

    IV. Bipolar cells are depolarized

    V. Action potential (impulse) is transmitted by optic nerves to visual cortex

    VI. Potential differences are generated in the photoreceptor cells

    VII. Light energy causes a change in shape of rhodopsin, leading to the dissociation of retinal (an aldehyde of vitamin-A) from opsin (a protein)

    VIII. Structure of opsin is changed

    Choose the correct sequence

    A

    I, II, III, IV, V, VI, VII, VIII

    B

    VIII, VII, VI, V, IV, III, II, I

    C
