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 […]

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 […]
