P.S Please  do not answer if its not complete or if you are not sure with the answer... thanks

Answer 1

Ans) b. Cofactor

Explaination:

Ferrous Iron can be oxidized to ferric iron, and ferric iron can be reduced to ferrous iron

By doing so, iron can serve as a cofactor to enzymes involved in the numerous oxidation-reduction reactions that commonly occur in all cells

2) a. Anaemia

Explaination:

Red blood cells carry oxygen to the body's tissues. As a result, iron deficiency anemia may leave you tired and iron deficiency anemia will eventually develop.

3) b. Phytate

Explaination:Phytate, which is present in staple foods like cereals, corn and rice, has a strong negative effect on zinc absorption from composite meals.

4) d. enzymes

Explaination:

Copper is part of many enzymes all of which play a metabolic role in reactions that consume oxygen or oxygen radicals.
