Explain the cellular and molecular mechanisms that determine the color of human skin.
Step by step
Solved in 2 steps
- As “naked apes” humans lack the protective investment of fur that shields other mammals from the damaging effects of sunlight. How does human skin respond to ultraviolet radiation in the short term and with continued exposure?Define pigmented layerFlamingos are not born pink, but through their diet absorb pigments that get deposited into their feathers which turns them from white to pink. Similarly, our own diet can effect the color of our skin if we were to eat high concentrations of food with absorbable pigments. For instance, if we ate a large amount of carrots and summer squash that contain beta-carotene, what color would you expect the skin to take on?' Yellow-green orange-green Yellow-orange Red
- What are the changes that occur in the human skin during the ageing process?What is the relationship between skin coloration and proximity to the equator? Explain in some detail, using technical termsDescribe the relationship between melanin and UV light exposure in the human population. Include a description of both the effects of UV light on a person and function of melanin.
