How do the features of Vitamins E and K cause them to be in a different cellular

Question

How do the features of Vitamins E and K cause them to be in a different cellular location than Vitamins B and C?

A. Their mass is too large to move through membrane transporters, unlike Vitamins B and C.

B. They are synthesized in endoplasmic reticulum, unlike Vitamins B and C, which are made in cytosol.

C. They have receptors on the plasma membrane, whereas Vitamins B and C have nulear receptors.

D. They are hydrophobic, so they are located in membranes rather than in the cytosol, like Vitamins B and C.

E. They are negatively charged, and are segregated in the plasma membrane rather than neutral as Vitamins B and C, which are found in many cellular locations.

Explanation / Answer

Answer: D. They are hydrophobic, so they are located in membranes rather than in the cytosol, like Vitamins B and C.

Explanations: Vitamin E and K are hydrophobic that is they are not charged. Moreover, they are always present in membranes. And vitamin B and C are located in cytosol. So, the correct answer is D.
