What do melanocytes produce? a type of protein used to form tough tissues a pigment that gives skin its color a protein found in skin that provides firmness and strength a waxy substance needed for hormone production

Answer 1

Melanocytes produce melanin, a pigment that gives skin its color and protects against UV radiation. The production of melanin increases with sunlight exposure to protect the skin but can affect vitamin D production if excessive.

Step-by-step explanation:

Melanocytes produce a pigment known as melanin, which gives skin its color. Melanin is essential for protecting the skin against ultraviolet (UV) radiation damage by absorbing and dispersing UV rays. The production of melanin increases with exposure to sunlight, leading to the darkening of the skin, or a tan. This process provides a protective barrier, safeguarding the DNA of epidermal cells from UV ray damage and the breakdown of folic acid. However, excessive melanin can also lead to reduced vitamin D production, which is vital for calcium absorption. The balance of melanin in the skin is therefore crucial for overall health.
