  1. The typical coenzyme present in the methanogenes is
    1. Coenzyme A
    2. Coenzyme Q
    3. Coenzyme M
    4. None of these
Correct Option: C

Coenzyme M is a coenzyme required for methyl-transfer reactions in the metabolism of methanogens. The coenzyme is an anion with the formula HSCH2CH2SO3. It is named 2-mercaptoethanesulfonate and abbreviated HS–CoM. The cation is unimportant, but the sodium salt is most available. Mercaptoethanesulfonate contains both a thiol, which is the main site of reactivity, and a sulfonate group, which confers solubility in aqueous media.
