BI110 Lecture Notes - Lecture 28: Light-Harvesting Complex, Light-Dependent Reactions, Photosystem I
Document Summary
Module 30 photosynthesis ii energy and sugars. Light harvesting complexes huge complex of that associate with chlorophyll molecules that can absorb light: when the chlorophyll in this complex absorbs light, it can only pass on the energy through inductive resonance. Chlorophyll are shown as the green diamonds within the proteins. Reaction centre complex is also made of proteins and pigment molecules: difference between this and light harvesting is reaction centre complex only associates with chlorophyll a special pair. Only these two types of chlorophyll can be oxidized (giving up energy by giving up electron) Given energy from the energy passed on from light harvesting complex or by. When electron is oxidized by chlorophyll a special pair, it is given to the primary electron absorbing light itself acceptor. Photosystem i absorbs 700nm light waves (p700) Photosystem ii absorbs 680 nm light waves (p680) Electron in p680 raised from ground state to excited state (p680*)
