The following points highlight the three main products of photosynthetic cell. The products are: 1. Starch 2. Sucrose 3. Amino Acids. Product # 1. Starch: The synthesis of starch and its regulation through ADP-glucose pyrophosphorylase has been vividly worked out and described in one of the earlier chapters. Recent studies have brought out that ratio of the activator glycerate-3-phosphate and [...]
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 [...]
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 [...]
