The second process involves a cyclic series of reactions named (after its discoverer) the Calvin Cycle. It is discussed in Photosynthesis: Pathway of Carbon Fixation. The details of the first process is ... Each molecule of oxygen released by the light reactions supplies the 4 electrons needed to make 2 NADPH molecules.
