Nitrogen gas is green, and photosynthesis uses N2 to run the Calvin cycle.B. Each chlorophyll molecule contains four nitrogen atoms that surround the Mg2+ ion, and these account formost of the nitrogen in a leaf.C. Nitrogen ions form the electrochemical gradient across the thylakoid membrane that drives ATP synthesis.D. Beta-carotene is composed largely of nitrogen atoms, and has a similar absorption to chlorophyll.
