C3 Photosynthetic Cycle 3. C4 Photosynthetic Cycle 4. C3 – C4 Intermediates 5. Role of C3 and C4 in Crop Productivity 6. Role of Light in Photosynthesis Control (Metabolic Regulation) [...]
The below mentioned article provides a study-note on the two pigments systems (Photosystems). The discovery of red drop and the Emerson's enhancement effect has led scientists to suggest that photosynthesis is driven by two photochemical processes. These processes are associated with two groups of photosynthetic pigments called as pigment system I and pigment system II. Wavelength of light shorter than [...]
In this article, we will discussion about the stoichiometry of the Calvin cycle. Stoichiometry is that part of chemistry which deals with the determination of combining proportions or chemical equivalents. Fig. 11.20 shows the simplified version of the Calvin Cycle. It is obvious from it that to produce one molecule of hexose sugar (6C), six molecules of CO2 are required. [...]
