Question

question 45.
which vitamin is manufactured in the body when skin is exposed to sunlight?
a. ○ vitamin a
b. ○ vitamin c
c. ○ vitamin d
d. ○ vitamin b

Explanation:

To determine the vitamin manufactured in the body upon skin exposure to sunlight, we recall biological knowledge: Vitamin D synthesis occurs in the skin when ultraviolet (UV) light from sunlight interacts with a precursor molecule (7 - dehydrocholesterol). Vitamins A, C, and B are not synthesized in this manner from sunlight exposure.

Answer:

C. vitamin D
