Selenium Which of the following minerals is associated with energy metabolism through electron transport chain? a. Calcium b. Iron c. Zinc d. Copper e.

(4).E more than one answer is correct IRON is used in fe-s complex which accept electron in complex I and ZINC is a antioxidant which maintain the membrane protien intergrity of mitochondria.
(5).D Folate is not associated with energy release .it is required for DNA ,RNA synthesis.
