The duplicate note says "Dihydrofolate may be converted to {{c1::tetrahydrofolate}} via the enzyme {{c2::dihydrofolate reductase}}"

Personally I think the above card is worded a bit better and is more helpful as it includes a cloze for the product of tetrahydrofolate. There are also two notes in the same format as the above card. (the other is 1476414676151).

The card I am suggesting to delete I believe is redundant. Thanks!
