Select the statement below that is not true with regards to the process of light adaptation.

Select one:

a. Rhodopsin is uncoupled from light transduction.

b. The activity of rods is reduced by rapid bleaching of rhodopsin.

c. Visual acuity is diminished.

d. Retinal sensitivity decreases.

c. Visual acuity is diminished.

Explanation:

Light adaptation is when the eye has to quickly adapt to illumination, during this five minutes process a phothochemical reaction takes place where rhodopsin decomposes into retinal + opsin, when light level increases, visual function shifts from the rod system to the cone system, therefore rods are reduced, another important fact is that visual acuity is greater through light adaptation and light sensitivity decreases.
