Question

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

Answer 1

Keratinocytes help protect the skin from UV damage by accumulating melanin granules, which forms a UV-blocking layer. The balance of melanin production is vital for protecting the skin's DNA while also maintaining proper levels of nutrients like folic acid and vitamin D.

Step-by-step explanation:

Melanocytes and keratinocytes work together in protecting the skin from UV damage when keratinocytes accumulate the melanin granules on their superficial portion, forming a UV-blocking pigment layer. Melanocytes are responsible for producing melanin, the pigment that gives color to the skin and helps protect it from UV radiation. Keratinocytes, the predominant cells in the epidermis, receive melanin from melanocytes and then move it to their superficial (upper) layers. There, the accumulated melanin forms a protective layer that absorbs and scatters UV radiation, preventing it from reaching deeper layers of the skin. This process is a crucial mechanism in the skin's defense against the harmful effects of UV radiation, including sunburn and the risk of skin cancer.

Answer 2

The answer would be: accumulate the melanin granules on their superficial portion, forming a UV-blocking pigment layer

The number of melanocyte cells is not much compared to keratinocytes. That is why melanocytes secrete dark melanin granules that will be spread into keratinocytes, not to itself.
The nutrient should be provided by the blood vessels of dermis skin. There should be no problem with pH or temperature either.
