Answer #1

Answer:

Transduction in photoreceptors is different from other types of receptors photoreceptors become hyperpolarised when stimulated whereas most of the other receptors are depolarized when stimulated. Moreover, when photoreceptors are not stimulated, inhibitory neurotransmitter glutamate is released continuously and this keeps photoreceptors inhibited but depolarized. As soon as light stimulus comes, inhibitory signal stops and photoreceptors become hyperpolarised. This is certainly not the case with other receptors which becomes depolarized when stimulated.
