What Reaction is Catalyzed by Mercuric Reductase

Question

What reaction is catalyzed by mercuric reductase?
A) CH₃HgCH₃ to Hg²⁺
B) CH₃Hg⁺ to Hg²⁺
C) Hg⁴⁺ to Hg²⁺
D) Hg²⁺ to Hg⁰

Accepted Answer

Mercuric reductase catalyzes the reduction of Hg²⁺ (mercuric ion) to Hg⁰ (elemental mercury), which is a key step in the bacterial mercury detoxification process.
