Which of the Following Contributes Most to Skin Color

Question

Which of the following contributes most to skin color?
A) hemoglobin
B) melanin
C) carotene
D) vitamin D
E) short-term acclimatization

Accepted Answer

Melanin is the pigment that contributes most to skin color. It is produced by melanocytes in the skin and absorbs UV radiation in order to protect the skin from damage. Hemoglobin is responsible for the red color of blood and does not contribute significantly to skin color. Carotene can give a slightly yellowish tint to the skin, but it is not a major contributor to overall skin color. Vitamin D is important for maintaining healthy skin, but it does not directly contribute to skin color. Short-term acclimatization can cause temporary changes in skin color, but it is not a major factor in determining overall skin color.
