Wu, Chem. explored the temporal dynamics of CFE on vegetation photosynthesis at the global scale. Respiration is not linearly related either to photosynthesis or to biomass, but it is more strongly controlled by recent photosynthates (and reserve availability) than by total biomass. Photosynthesis is the transformation of light energy to chemical energy. But through our efforts, we have been able to make the electron switch to an alternate path 90 percent of the time. For instance, artificial photosynthesis is an effective way to split H 2 O into molecular O 2 and H 2, thereby storing solar energy in the form of hydrogen fuel.
