In chloroplasts, when the two photosystems work in series, electrons ejected from the photosystems do not return to them, which

When electrons do not return to the photosystems, it is because of a process known as oxygenic photophosphorylation, a process that is key to photosynthesis.

Photosynthesis is the process by which plants get their energy. This process involves many steps taken in order to turn energy from light, into sugar and molecular energy known as ATP, needed for plants to survive. This process uses a variety of important and complex steps, among which is included oxygenic photophosphorylation.

Oxygenic photophosphorylation is one of the key processes to photosynthesis. It involves the use of photosystems one and three, located in the thylakoid membrane of plant cells, in order to produce NADPH and ATP. These systems enter a state of photoactivation, releasing an electron to be carried by the NADPH molecule towards the Calvin cycle where the electron can be placed onto a carbon atom, for long-term storage, often as a carbohydrate.
