Question

Quizplus · Accepted Answer

Vitamin B₁₂ and folate deficiencies both may promote the development of macrocytic anemia because they are involved in DNA synthesis, and loss of either results in the impaired production of red blood cells. Homocysteine is a product of methionine metabolism. Levels of homocysteine increase when vitamin B₁₂and folate are deficient because these are necessary for its conversion back to methionine. Vitamin B₆ affects homocysteine by converting it to cysteine. However, neither of these promote anemia. Iron is associated with microcytic anemia.
