Absorption of vitamin E is through _____.Multiple choice question.passive diffusionactive transport

The absorption of vitamin E primarily occurs through passive diffusion.

Explanation:

Vitamin E is a fat-soluble vitamin, which means that its absorption is closely related to the presence of dietary fats. The process begins in the intestine, where vitamin E is incorporated into micelles formed by bile salts and dietary fats. This formation facilitates the passive diffusion of vitamin E across the intestinal cell membranes, where it can then enter the bloodstream. Passive diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration without the need for energy or transport proteins.

Active transport, on the other hand, usually involves the use of energy to move substances against their concentration gradient, which does not apply to vitamin E absorption.

Final Answer:

The absorption of vitamin E is through passive diffusion.
