  • Illustration of molecules crossing a cellular membrane.

    Photosynthetic Electron Transport Chain

    An overview of steps involved in using light energy to produce carbohydrates or hydrogen: (1) light absorption by photosystem II initiates the photosynthetic pathway; (2) electron transport through the cytochrome complex generates a πroton gradient; (3) light absorption by photosystem I excites electrons and facilitates electron transfer to an electron acceptor outside the thylakoid membrane; (4) under certain conditions, ferredoxin can carry electrons to hydrogenase; and (5) dissipation of proton gradient is used to synthesize adenosine triphosphate (ATP).

  • Gene function goes from the genome to ecosystem level.

    Gene Function Across Multiple Scales

    Understanding gene function across multiple levels of biological organization is a key objective of the Department of Energy’s Genomic Science program.

  • Examples of DNA for genomics, RNA for transcriptomics, proteins for proteomics, and metabolites for metabolomics.
