Methanogenic archaea live at the thermodynamic limit of life and use sophisticated mechanisms for ATP synthesis and energy coupling. The group of methanogens without cytochromes use an Na(+) current across the membrane for ATP synthesis, whereas the cytochrome-containing methanogens have additional coupling sites that also translocate protons. The ATP synthase in this group is promiscuous and uses Na(+) and H(+) simultaneously.
产甲烷古菌生活在生命的热力学极限下，它们使用复杂的机制来进行 ATP 合成和能量偶联。不含有细胞色素的产甲烷菌群利用跨膜的钠离子电流来进行 ATP 合成，而含有细胞色素的产甲烷菌群则具有额外的偶联位点，也可以转运质子。这个菌群中的 ATP 合酶是混杂的，同时使用钠离子和氢离子。
