- What is nitrogen fixation? What are the proteins involved? How do they participate in the fixation of Nitrogen? Why is nitrogen fixation so energetically costly?What is nitrogen fixation?what are proteins involved?how do they participate in fixation nitrogenDefine nitrogen fixation. What organisms are capable of nitrogen fixation?
- What is the Function of Leghaemoglobin in nitrogen fixation.Why must nitrogen fixation occur in an anoxic (i.e., oxygen-free) environment? a)Because H2 is an additional product of nitrogen fixation, and the combination of H2 and O2 would cause the cell to combust. b)Oxygen poisons the dinitrogenase enzyme by entering the FeMo cluster c)Oxygen competes as an electron acceptor in the ETC, so electrons cannot be passed to N2. d)Oxygen "steals" electrons from the dinitrogenase reductase, producing free radicals.What is the nitrogencycle?
- Regarding nitrogen fixation, are the following statements True or False? a) Atmospheric nitrogen is reduced to the biologically useful form NH3 (or NH4 ). b) Nitrogen fixation in nature and in the lab requires a metal cofactor or catalyst. c) The availability of fixed nitrogen limits biological productivity. d) Ammonium from the atmosphere is fixed to more usable forms of nitrogen, such as nitrite (NO2–). e) Nitrogen fixation is energetically neutral, using a negligible amount of ATP. f) The enzyme nitrogenase, which takes part in nitrogen fixation, is inactivated by oxygen.Only select prokaryotic organisms can harvest energy from food by oxidative phosphorylation, but can do this in the absence of oxygen. These organisms are using: a) Aerobic respiration b) Carbon fixation c) Fermentation d) Anaerobic respiration e) PhotophosphorylationWhat are the necessary conditions for autotrophic nutrition and what are its by-products.
- What is cistron?What is nitrogen assimilation? What is the acceptor molecule? What does it react with? What is the product?Heterotophs... a) do not require a carbon source. b) use organic compounds, like starch, as a carbon source. c) use carbon dioxide as their carbon source. d) require light for metabolic reactions.
