Back to all questions 11
Question The fibrous structural protein, keratin is found in (P) ............... and a pigment melanin is contained in (Q) ............... of the epidermis.
- P — Malpighian layer, Q — Cornified layer
- P — Stratum malpighi, Q — Granular layer
- P — Stratum corneum, Q — Germinative layer
- P — Granular layer, Q — Cornified layer
P — Stratum corneum, Q — Germinative layer
Reason — Keratin is a fibrous structural protein that provides protection and waterproofing to the skin. It is found in the stratum corneum, the outermost layer of the epidermis, made up of dead, keratinized cells.
Melanin is the pigment responsible for skin color and UV protection. It is present in the germinative layer, the innermost layer of the epidermis.
