Question

Who provides color to the skin?

• A. Melanin
• B. Keratin
• C. Albumin
• D. Chitin

Hint:

The amount and type of melanin are influenced by genetic factors and exposure to sunlight.

Answer 1

The Correct Option is A

In biology, the color of human skin is primarily determined by a pigment called melanin. Melanin is produced by specialized cells called melanocytes, which are found in the epidermis, the outermost layer of the skin. The amount and type of melanin produced by these cells influence the color of a person's skin, eyes, and hair.

The more melanin present, the darker the skin. Melanin serves multiple functions, including protecting the skin from the harmful effects of ultraviolet (UV) radiation from the sun. Here is an explanation of the options:

Option	Description
Melanin	This pigment is responsible for the color of skin, hair, and eyes and provides protection against UV radiation.
Keratin	A protein that strengthens hair, nails, and the outer layers of skin, but does not provide color.
Albumin	A protein found in blood plasma, unrelated to skin color.
Chitin	A component of the exoskeletons of arthropods and fungi; not involved in human skin pigmentation.

Based on this explanation, the correct answer to the question "Who provides color to the skin?" is Melanin.
