Which of the following are functions of vitamin E in the body? Check all that apply. Check All That Apply Releasing energy from macronutrients Releasing energy from macronutrients Maintaining nervous tissue Maintaining nervous tissue Calcifying boneCalcifying bone Protecting cell membranes from oxidative damage Protecting cell membranes from oxidative damage Maintaining immune system function
The Correct Answer and Explanation is :
The correct functions of vitamin E in the body include:
- Maintaining nervous tissue
- Protecting cell membranes from oxidative damage
- Maintaining immune system function
Explanation:
Vitamin E is a fat-soluble antioxidant that plays crucial roles in maintaining overall health. Here’s how it functions in the body:
- Maintaining Nervous Tissue
Vitamin E is essential for the proper functioning of the nervous system. It helps protect neurons from oxidative damage by neutralizing free radicals. This is critical for maintaining the integrity of nerve cells and preventing degenerative conditions. - Protecting Cell Membranes from Oxidative Damage
One of vitamin E’s primary roles is as an antioxidant. It protects the lipids in cell membranes from oxidative stress caused by free radicals, which are unstable molecules that can cause cell damage and contribute to aging and disease. This function is especially important in cells with high oxygen content, such as red blood cells and lung cells. - Maintaining Immune System Function
Vitamin E supports the immune system by enhancing the activity of immune cells, such as T-cells, which are crucial for fighting infections. It helps modulate the inflammatory response and maintain a robust defense against pathogens.
Why the Other Options Are Incorrect:
- Releasing Energy from Macronutrients
This is primarily a function of B-complex vitamins (e.g., B1, B2, B3) and not vitamin E. - Calcifying Bone
Bone calcification is primarily regulated by vitamin D, calcium, and phosphorus, not vitamin E.
Vitamin E is found in foods like nuts, seeds, vegetable oils, and green leafy vegetables. Deficiency is rare but can lead to issues like nerve and muscle damage, weakened immunity, and oxidative stress-related conditions. Maintaining adequate vitamin E levels is vital for overall health and longevity.
