Step-by-step explanation:
The statement that is true about vitamin E and vitamin C is:
- Vitamin C can regenerate vitamin E.
Vitamin E and vitamin C are both important antioxidants that play a role in protecting cells from oxidative damage caused by free radicals. While they have separate functions, they can also work together synergistically.
Vitamin C has the ability to regenerate or recycle vitamin E after it has neutralized a free radical. Once vitamin E has donated an electron to stabilize a free radical, it becomes oxidized. However, vitamin C can reduce the oxidized form of vitamin E, effectively regenerating its antioxidant properties and allowing it to continue its protective role.
The other statements mentioned are not accurate:
- While both vitamins can be found in cell membranes to some extent, it is not true to say that they are both exclusively found in cell membranes.
- Vitamin E can be regenerated by vitamin C, but the reverse is not true. Vitamin E does not have the ability to regenerate vitamin C.
- While both vitamins are found in certain foods, they are not exclusively abundant in lipid-rich foods or fruits. Vitamin E is commonly found in vegetable oils, nuts, and seeds, while vitamin C is abundant in citrus fruits, strawberries, and other fruits and vegetables.
