The electron flow generates a higher concentration (charge) of positively-charged hydrogen (H+) ions (or protons) ... tube. In an intact chloroplast with thylakoid membranes, ATP is generated by an electron flow along the cytochrome transport system. Since the electrons are being transported to other " ...

... The Z scheme shows the pathway of electron transfer from water to NADP+. Using this pathway, plants transform light energy into "electrical" energy (electron flow) and hence into chemical energy as ... excitation of reaction center chlorophyll molecules (by light energy) and the black arrows represent electron flow, which is downhill energy-wise. This particular version of the "Z-scheme" was developed ...
