Question 4

OTHER
Statement Completion
Complete the statements by choosing the correct response in the parentheses.
-When light of suitable wavelength strikes a photoreceptor, the photopigment (absorbs or reflects) the light, causing the photopigment to (dissociate or regenerate). This photopigment transformation acts through a second messenger system to cause Na+ channels in the outer segment to (open or close). Subsequently, the photoreceptor (depolarizes or hyperpolarizes), which results in a(n) (increase or decrease) in release of an (excitatory or inhibitory) transmitter from its synaptic terminal.

Accepted Answer

absorbs, dissociate,
