Question

Which of the following accurately describes fat-soluble vitamins?

Answer 1

Answer:

d. Deficiency symptoms sometimes take a year or more to develop on a poor diet.

Explanation:

Fat soluble vitamins are vitamins that can be stored in the body for a long time, they are more toxic than water soluble vitamins. These vitamins include vitamin A, vitamin D, vitamin E and vitamin K.

The fat soluble vitamins don't circulate freely in water filled parts of the body, because they are stored in fat-associated cells.

The fat soluble vitamins don't travel freely in the blood because transport proteins are needed for its movement unlike that of water soluble vitamins that move freely.

The kidneys detect and remove excesses in urine only in water soluble vitamins not in fat soluble vitamins.

The fat soluble vitamins are not needed in doses everyday as the body stores the unused vitamins in the liver.

Without proper amount of fat soluble vitamins present in the body, symptoms of deficiency can develop on a poor diet, but they take time before developing.
