The following points highlight the six main steps involved in nitrogen cycle. The steps are: 1. Nitrogen Fixation 2. Nitrogen Assimilation 3. Ammonification 4. Nitrification 5. Denitriflcation 6. Sedimentation. Nitrogen Cycle: Step # 1. Nitrogen Fixation: Conversion of free nitrogen of atmosphere into the biologically acceptable form or nitrogenous compounds is referred to as nitrogen flxation. This process is of [...]
In this article we will discuss about the Mechanism and Importance of Anaerobic Respiration in Plants. Mechanism of Anaerobic Respiration: It is the process of release of energy in enzymatically controlled step-wise incomplete degradation of organic food without oxygen being used as oxidant. Therefore, end products are never completely inorganic. The term anaerobic respiration is often used in connection with [...]
The following points highlight the three steps involved in aerobic respiration in plants. The steps are: 1. Glycolysis 2. Krebs cycle 3. Terminal Oxidation. Step # 1. Glycolysis (Gk. glycos - sugar, lysis - splitting, Fig. 14.2): It is also called ЕМР pathway because it was discovered by three German scientists— Gustav Embden, Otto Meyerhof and J. Pamas in 1930.
