All of the following statements concerning folic acid are true except: A) N⁵,N¹⁰-methylene THF is a product of the cleavage of glycine. B) Vitamin B12is required for the N⁵-methyl THF-dependent conversion of homocysteine to methionine. C) N¹⁰-formyl THF, CO2, and aspartate are precursors in the synthesis of hypoxanthine D) Folic acid is a B vitamin. E) Folic acid requires intrinsic factor for its absorption in the intestine.

Accepted Answer

Folic acid does not require intrinsic factor for its absorption; vitamin B12 does. Intrinsic factor is a protein necessary for the absorption of vitamin B12, not folic acid.
