Fill in the blanks to make the statements all true; “melanin is produced in an organelle called     melanin is derived from an amino acid       the enzyme that converts into   melanin is     this enzyme is activated by   light.    in the inherited condition known as   the melaninocytes cannot synthesize tyrosinase, so   skin, hair, and eyes lack melanin.

Melanin is a pigment responsible for skin color in most of the organisms. It is produced when amino acid Tyrosine oxidizes and then undergoes ploymerization to form melanin. Tyrosinase is an enzyme which gets activated by UV rays and converts amino acid to melanin.

Melanin is produced in an Organelle called Melanocytes.  Melanin is derived from an amino acid called Tyrosine.  The enzyme that converts Amino acid Tyrosine into Melanin is Tyrosinase.  This enzyme is activated by Ultra Violet Light.  In the inherited condition known as Albinism the melaninocytes CANNOT synthesize tyrosinase, so Skin, hair, and eyes lack melanin.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
