What processes allow an eye to properly adjust to a dim environment?

Question

Quizplus · Accepted Answer

All of the choices listed contribute to the eye's adjustment to a dim environment. A) The dilation of pupils allows more light to enter, enhancing vision in low light. B) The replacement of photobleached retinal with non-photobleached cis-retinal is crucial for the regeneration of the photoreceptors' sensitivity. C) The role of calcium and cGMP in phototransduction indirectly influences the eye's adaptation to darkness, although the statement about calcium's role is somewhat misleading in this context, as lower calcium levels in darkness actually promote cGMP synthesis, enhancing the sensitivity of photoreceptors. Despite the slight inaccuracy in C's description of the mechanism, all options are involved in the adaptation process.
