The below mentioned article provides a study note on the C4-Dicarboxylic Acid Pathway. C4-Dicarboxylic Acid Pathway (Hatch Slack Pathway, C4 Pathway): It was worked out by Hatch and Slack (1965, 1967). However, initial discovery was made by Kortschak (1965) who found that labelled carbon dioxide (14CO2) assimilated by Sugarcane leaves first appeared in a 4-carbon compound […]

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 […]
Primary and Secondary Reactions of Photosynthesis

In this article we will discuss about the primary and secondary reactions of photosynthesis. Ruben and his co-workers in early 1943 used 18O and proved that oxygen evolved in photosynthesis came from water. Photosynthesis allowed to proceed in H2O18 and normal CO2, had molecular oxygen evolved with heavy isotopes. When photosynthesis was carried out in […]
