Learn about the comparison between Non-Cyclic and Cyclic Photophosphorylation. Comparison # Non-Cyclic Photophosphorylation: In this a photon of light is involved to excite electron in chlorophyll b or other accessory pigments of photosystem II. Energy of two such excited electrons is accepted by an oxidized plastoquinone forming completely reduced plastoquinone and electron-deficient chlorophyll b (Chl b). Chl b then accepts [...]
The minimum number of molecules of pigment and other associated compounds which are capable of converting a quantum is known as photosynthetic unit. When the electron microscopy revealed quantasomes on the lamellae of the chloroplast, most of the scientists believed that they had discovered a photosynthetic unit. However, Anderson and Boardman (1966) first of all raised the question whether the [...]
In this article we will discuss about the subject-matter and components of electron transport chain. Subject Matter of Electron Transport Chain: The primary function in photosynthesis is the raising of an electron to a higher energy level in chlorophyll. Then the electron is transferred to an acceptor. It is, as if, there is a hole in the chlorophyll which invites [...]
