WebJul 3, 2024 · Quick Review of the Key Concepts of Photosynthesis. In plants, photosynthesis is used to convert light energy from sunlight into chemical energy (glucose). Carbon dioxide, water, and light are used to make glucose and oxygen. Photosynthesis is not a single chemical reaction, but rather a set of chemical reactions. The overall reaction is: WebJul 5, 2024 · Steps involved in photosystem: When a photon hit photosystem II, light energy absorbed by one of the pigments in photosystem II, energy is carried from one pigment to …
WebPhotosystem I (PSI) is one of the key players in the process of oxygenic photosynthesis. This large membrane protein complex utilizes light energy to transfer electrons from the lumenal electron carriers plastocyanin or cytochrome c6 across the photosynthetic membrane to the stromal/cytosolic electron carriers ferredoxin or flavodoxin.
