Many Euryarchaeota are methanogens; which of the following statements is true?Group of answer choicesMethanogens produce methane as a part of their energy metabolismMethanogens utilize methane as an energy source.Methanogens process and store methaneMethanogens are useful in bioremediation because they can break down methane
Solution
The true statement is: Methanogens produce methane as a part of their energy metabolism.
Here's why: Methanogens are a type of archaea that produce methane as a byproduct of their metabolism. This process, known as methanogenesis, involves the reduction of carbon dioxide to methane using hydrogen. This is how they generate energy for their growth and survival.
On the other hand, methanogens do not utilize methane as an energy source, nor do they process and store methane. While methanogens are involved in the carbon cycle and can indirectly influence bioremediation processes, they do not break down methane - they produce it.
