Melanocytes and keratinocytes work together in protecting the skin from UV damage when keratinocytes ________.
A) provide the melanocyte with nutrients necessary for melanin synthesis
B) accumulate the melanin granules on their superficial portion, forming a UV-blocking pigment layer
C) maintain the appropriate pH in order for the melanocyte to synthesize melanin granules
D) maintain the appropriate temperature so the product of the melanocyte will not denature

Question

Quizplus · Accepted Answer

Keratinocytes accumulate melanin granules on their superficial portion, forming a UV-blocking pigment layer, which helps protect the skin from UV damage. Melanocytes produce melanin, which is then transferred to keratinocytes for distribution in the skin. However, melanocytes do not rely on keratinocytes for nutrients or pH maintenance, and temperature is not a significant factor in melanin synthesis.
