Question

Quizplus · Accepted Answer

Rhodopsin is the pigment in the retina that enables vision in low-light conditions by absorbing light at a wavelength of around 498 nm. It takes time for the regeneration of rhodopsin after it has been broken down by light, which is why BJ experienced night blindness until adequate levels of rhodopsin could be resynthesized. Options A, B, and D are not relevant to low-light vision.
