Photoreceptors of Photosynthetic Pigments

The following points highlight the seven main types of photoreceptors of photosynthetic pigments. The photoreceptors are: 1. Phycobilins 2. Cryptochrome 3. UV-B Receptors 4. Flavonoids 5. Betacyanins 6. Chloroplasts 7. Carotenoid Pigments. Photoreceptor # 1. Phycobilins: These are present in red algae, cyanobacteria or even green plants and serve as accessory light- harvesting pigments. Four phycobilins are reported; three are [...]

3 Main Products of Photosynthetic Cell

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 [...]

Non-Cyclic and Cyclic Photophosphorylation | Photosynthesis

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 [...]
