High-Yield Explanation
Ans. (c) Methionine synthaseRef.: Harpers Biochemistry 30th edn. 1558B CONVERSION OF HOMOCYSTEINE TO METHIONINE* Active form in this reaction is methycobalamin. This reaction requires both methylcobalamin and folic acid. The reaction is catalyzed by methionine synthase which is a methylcobalamin dependent reaction.HomocysteineMethionine synthase-------------------------Methylcobalamin + folic acidMethionine
