Why does cyclic phosphorylation occur

Cyclic Photophosphorylation. Non-Cyclic Photophosphorylation. Cyclic vs Non-Cyclic Photophosphorylation. The key differences between cyclic and non-cyclic photophosphorylation are summarised in the table below:.

Evolution Evidence 2. This splitting of water is responsible for the release of O 2 into the air. Each photoexcited electron energized by light passes from the primary electron acceptor in photosystem II to photosystem I via an electron transport chain. This electron transport chain is very similar to the one in cellular respiration; however, the carrier proteins in the chloroplast ETC are different from those in the mitochondrial ETC.

The production of ATP in the chloroplast is called photophosphorylation because the energy harnessed in the process originally came from light. This process of ATP production is called non-cyclic photophosphorylation. The ATP generated in this process will provide the energy for the synthesis of glucose during the Calvin cycle light independent reactions.

The hole was created when light energy drives an electron from P to the primary electron acceptor of photosystem I. The primary electron acceptor of photosystem I passes the excited electrons to a second electron transport chain which transmits them to an iron-containing protein. Cyclic vs.
