Steps 1 – 6 : This is called noncyclic electron flow because it requires light and water to start it each time. The ATP made is called noncyclic photophosphorylation When the cell has too many NADPH, it will switch to cyclic electron flow which just uses photosystem I and only generates ATP.

Cyclic Electron Transport in Photosynthesis
These paths are known as cyclic electron flow and non-cyclic electron flow. In cyclic electron flow, electrons begin at the acceptor molecule and are passed to an electron transport chain. This ETC, like the one connecting the two Photosystems, is a series of receptor molecules able to pass along electrons.

In these species, which include the purple sulfur bacteria, cyclic electron flow is the sole means of generating ATP in photosynthesis. Evolutionary biologists hypothesize that these bacterial groups are descendants of the bacteria in which photosynthesis first evolved, in a form similar to cyclic electron flow.

The cyclic electron pathway utilizes only Photosystem I and produces only ATP. It probably evolved before Photosystem II. This is a primitive type of photosynthesis found in certain photosynthetic bacteria and in photosynthetic eukaryotes, including plants. 7.9 Noncyclic Electron Flow Uses Two Photosystems And Generates ATP, NADPH, And O2
