How would a diet low in selenium affect a cell's ability to deal with oxidative stress? A)Low selenium will reduce levels of superoxide dismutase,an enzyme that converts hydrogen peroxide to water.This will increase the need for vitamin E. B)Low selenium will reduce levels of glutathione peroxidase,an enzyme that converts hydrogen peroxide to water.This will increase the need for vitamin E and vitamin C. C)Low selenium will increase levels of glutathione peroxidase,an enzyme that converts hydrogen peroxide to water.This will decrease the need for vitamin E and vitamin C D)Low selenium will reduce levels of glutathione peroxidase,an enzyme that converts water to hydrogen peroxide.This will increase the need for vitamin C.

Selenium is a cofactor for glutathione peroxidase, an enzyme that reduces hydrogen peroxide to water, helping to protect the cell from oxidative damage. A deficiency in selenium would reduce the activity of this enzyme, not superoxide dismutase, and increase the need for antioxidants like vitamin E and vitamin C to compensate for the increased oxidative stress.
