Question

question 10
besides food, what is another source of vitamin k?

○ breakdown of bones in the body

○ bacterial production in the large intestine

○ fungal production in the intestines

○ sunlight exposure

Explanation:

Vitamin K can be produced by bacteria (specifically some gut bacteria) in the large intestine. Bone breakdown doesn't produce vitamin K, fungal production in intestines isn't a main source, and sunlight is for vitamin D, not K. So the correct source besides food is bacterial production in the large intestine.

Answer:

B. Bacterial production in the large intestine
