7.7 The Earliest Phosphorites: Radical Change in the Phosphorus Cycle During the Palaeoproterozoice macro-molecules are involved in energy transport, information storage, and structural support functions include membrane lipids, proteins, and nucleic acids. The global phosphorus cycle, which includes only dissolved and solid phases without any gaseous components, is strongly influenced by biolog
