Which of the following is a non-heme function of iron?
A)Bone turnover
B)Reduction of oxidative stress
C)Keratin biosynthesis
D)Deactivation of ATP

Question

Quizplus · Accepted Answer

Iron can also act as an antioxidant and reduce oxidative stress by donating or accepting electrons in various enzymatic reactions. This is a non-heme function of iron. The other choices (A, C, and D) are heme-dependent functions of iron. Iron is a component of heme, which is necessary for the formation of hemoglobin, myoglobin, and cytochromes. Bone turnover, keratin biosynthesis, and ATP deactivation all require heme-dependent enzymes.
