In this article we will discuss about Photosynthetic Antenna Pigments. After reading this article you will learn about: 1. Composition of Photosynthetic Antenna Pigments 2. Role of the Antenna in Photosynthesis. Composition of Photosynthetic Antenna Pigments: All functional pigments in photosynthetic membranes are bound in a variety of pigment-protein complexes. In general, photosynthetic pigments and pigment-protein complexes serve two primary [...]

Learn about the Difference between Photorespiration and Dark Respiration. 1. In practically all aerobic tissues, dark respiration is a common feature. On the other hand, photorespiration is demonstrated only by those plants in which carbon fixation occurs via the C3 cycle. 2. In dark respiration, O2 uptake is restricted to only one kind of organelle, the mitochondrion, whereas O2 uptake [...]

The below mentioned article provides a study notes on Pathway of Crassulacean Acid Metabolism (CAM). Schemes showing the different pathways or patterns of CAM are shown in Fig. 8.28. CO2 fixation pathway in dark requires the breakdown of starch to produce PEP, the substrate for carboxylation by PEPcase. Like C4 plants, this enzyme catalyzes the reaction of PEP with CO-3 [...]
