Answer and Explanation:1 Nitrogen exists in two forms in the environment: inorganic and organic. The process of conversion of nitrogen to its various chemical forms is known... Learn more about this topic: Ammonification: Definition & Nitrogen Cycle ...
Other Processes of the N-Cycle Nitrogen mineralization is the process by which inorganic nitrogen is obtained by decomposition of organic N-compounds. Extracellular proteolytic enzymes of saprophytic bacteria and fungi are responsible for protein degradation to small peptides and amino acids, which are ...
Plants cannot directly use atmospheric nitrogen gas. Thus, nitrogen in the soil is transformed through the nitrogen cycle.Answer and Explanation: The nitrogen cycle is the biogeochemical cycle that describes how nitrogen (N) is transformed and recycled in the environment. The nitrogen cycle is......
cycle in N-poor peridotitic mantle. Oxidation of fluids strongly reduces the concentration of CH4and bulk carbon. However, higher alkanes, alcohols, and carboxylic acids can resist oxidation and should remain stable in mantle hydrous magmas.
For instance, acetate can be directly converted into acetyl-CoA from acetyl-CoA synthetase (ACS), and incorporate immediately into the TCA cycle or used in FA synthesis by C. reinhardtii34. Likewise, Chlorella grown in acetate medium use ACS to directly incorporate acetate into acetyl-CoA, by-...
Therefore, the behaviour of CH3N may control the nitrogen cycle in N-poor peridotitic mantle. Oxidation of fluids strongly reduces the concentration of CH4 and bulk carbon. However, higher alkanes, alcohols, and carboxylic acids can resist oxidation and should remain stable in mantle hydrous ...
thereby distinguishing itself from the natural nitrogen cycle [9,69]. The direct photocatalytic conversion of N2to HNO3, facilitated by solar energy, represents an environmentally advantageous alternative to traditional multi-stage synthesis methodologies. However, the underlying mechanisms pertaining to the...
The main explanation is that ammonia decomposition is also controlled by kinetic factors, with higher reaction activation energy leading to lower reaction rates. There is no consensus among researchers on the rate-limiting step for ammonia decomposition. Under different conditions, the rate-limiting ...
