A bacterium capable of producing methane and water from carbon dioxide and hydrogen performs a type of metabolism called __________ and, given its sources of electrons, it is a __________.

Question

Quizplus · Accepted Answer

The production of methane and water from carbon dioxide and hydrogen is characteristic of methanogenesis, which is a type of metabolism performed by methanogenic archaea. These organisms obtain energy by oxidizing hydrogen gas and reducing carbon dioxide to methane gas. This type of metabolism is chemolithotrophic, as it relies on the oxidation of inorganic molecules (i.e. hydrogen gas) to generate ATP.
