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 temperature so the product of the melanocyte will not denature
D) maintain the appropriate pH in order for the melanocyte to synthesize melanin granules

Question

Quizplus · Accepted Answer

Keratinocytes accumulate the melanin granules on their superficial portion, forming a UV-blocking pigment layer that protects the skin from UV damage. Melanocytes, on the other hand, produce melanin granules in response to UV exposure. Therefore, the combination of melanocytes and keratinocytes is important for protecting the skin from UV damage.
