How do Melanocytes Make Melanin?: Melanogenesis Mechanism

The video explains how keratinocytes receive increased pigmentation through melanin production when exposed to sunlight, leading to tanning. It details the structure of skin layers, the role of keratinocytes and melanocytes, and the process of melanin production triggered by UV light. The protective role of melanin in shielding DNA from UV damage is highlighted, along with the differences in baseline melanin levels among ethnicities.

What role do keratinocytes play in the process of tanning?

Explain the process by which melanin is produced in response to UV exposure.

What is the function of the protein P53 in the context of DNA damage?

Describe how alpha melanocyte stimulating hormone (alpha MSH) affects melanin production.

What is the significance of melanosomes in the tanning process?

How does melanin protect the DNA in keratinocytes from UV damage?

Discuss the differences in baseline melanin levels among different ethnicities.
