100 rhodopsins are bleached with photons of light. After 5 minutes, how many have recovered and are now unbleached?

Explanation:
The test is about how rhodopsin recovers after bleaching. When rhodopsin is bleached by light, it must go through the retinoid cycle to regain its light-detecting form, a process that happens slowly in darkness. After about five minutes, roughly half of the bleached molecules have regenerated to the unbleached form. So, from 100 bleached rhodopsins, about 50 would have recovered and become unbleached. The rest are still in the process of regeneration and would take longer to return to the unbleached state.
