论文摘要
根据Panspermia或Nebula-Relay假设等模型，地球上生命的祖先曾经生活在分子云中。那么，这种生命形式的能源和生物能源是什么？在本文中，我们提出了一种由氢分子的宇宙射线电离驱动的新生物能机制，我们认为它可能与化学症的起源有关或是化学症的起源。基于这种机制，我们建议最后一个通用的普通祖先是一种利用氢分子作为电子传输链的供体的生命形式。
According to models such as panspermia or the Nebula-Relay hypothesis, the ancestors of life on Earth once lived in molecular clouds. Then what are the energy source and bioenergetics for such lifeforms? In this paper, we propose a new bioenergetic mechanism powered by cosmic ray ionization of hydrogen molecules and we argue that it may relate to or be the origin of chemiosmosis. Based on this mechanism, we suggest that the Last Universal Common Ancestor is a type of lifeform that utilize hydrogen molecules as donors of electron transport chains.
