Question

Quizplus · Accepted Answer

Methanogenesis is the most ancient form of metabolism on Earth, and it involves the production of methane by microorganisms that live in anaerobic environments. Methane-producing archaea are thought to have been some of the first living organisms on Earth over 3.5 billion years ago, and they continue to play a key role in the global carbon cycle. Glucogenesis and lipogenesis are metabolic pathways that involve the synthesis of glucose and lipids, respectively, and are not as ancient as methanogenesis. Oxygenesis and carbonogenesis are not recognized terms in the field of metabolism.
