After 30 minutes of sun exposure, which of the following people would have synthesized more vitamin D?

Question

Quizplus · Accepted Answer

This is because light-skinned people are able to synthesize more vitamin D than dark-skinned people in the same amount of time due to the higher levels of melanin in darker skin, which can interfere with vitamin D synthesis. Therefore, a light-skinned person would synthesize more vitamin D in 30 minutes of sun exposure. Light-skinned people synthesize vitamin D more efficiently than dark-skinned people, as melanin pigment in the skin blocks UVB radiation, which is necessary for vitamin D synthesis. Therefore, after 30 minutes of sun exposure, the light-skinned person would have synthesized more vitamin D.
