Notes from NEET topper
- Non-Cyclic Photophosphorylation:
- Non-cyclic photophosphorylation involves both Photosystem I and II.
- It results in the production of ATP, NADPH, and oxygen.
- The process starts with Photosystem II absorbing light and losing an electron, which is then passed to Photosystem I.
- The missing electron in Photosystem II is replaced by splitting a water molecule, releasing oxygen as a by-product.
- The high-energy electron from Photosystem II is passed through an electron transport chain to Photosystem I, producing ATP in the process.
- Photosystem I also absorbs light and transfers its high-energy electron to NADP+, reducing it to NADPH.
