Because the oxygen concentration was too low during dark reactions of plants, a swift decline of current was observed but it was gradually increased as the rate of photosynthesis and oxygen increased during day times.
Once produced, these energy-rich compounds must then migrate to the energy transfer point in the leaf and release their energy to drive the light-independent reactions or dark reaction in the chloroplast stoma to convert carbon dioxide into glucose through a complex series of reactions that all first-year biology students learn as the Calvin Benson cycle.
We've been able to separate the light reaction from the dark reaction and instead of using biological photosynthesis, we are using solar panels to convert the sunlight to electrical energy, then to a chemical intermediate, and using that to power carbon dioxide fixation to produce the fuel," Liao said.
In truth, the so-called dark reaction usually takes place in the presence of light, but light is not required.
