What do nitrogen fixing bacteria use to split molecules of nitrogen gas and combine the nitrogen atoms with hydrogen?
Nitrogenase enzyme is used by nitrogen fixing bacteria to split molecules of nitrogen gas and combine the nitrogen atoms with hydrogen.Nitrogenase is the enzyme used by some organisms to fix atmospheric nitrogen gas (N2). It is the only known family of enzymes which accomplishes this process
Why only prokaryotes have ability to fix atmospheric nitrogen?
Only prokaryotes can fix atmospheric nitrogen due to the presence of the nitrogenase enzyme, which is essential for converting nitrogen gas (N₂) into ammonia (NH₃). This process occurs in specialized cells or structures, such as root nodules in legumes, where prokaryotes like Rhizobium live symbiotically with plants. Eukaryotes lack the necessary biochemical pathways and the nitrogenase enzyme, making them incapable of directly fixing atmospheric nitrogen. Consequently, prokaryotes play a crucial role in the nitrogen cycle and ecosystem nutrient dynamics.
What is nitroginase?
Nitrogenase is an enzyme responsible for the biological conversion of atmospheric nitrogen gas into ammonia, which can be used by plants to synthesize essential biomolecules like proteins and nucleic acids. This process is called nitrogen fixation and is crucial for the nitrogen cycle in ecosystems.
Function of heterocyts found in cynaobacteria?
Heterocysts are specialized cells in cyanobacteria that are responsible for nitrogen fixation. They provide an anaerobic environment for the nitrogenase enzyme to function, converting atmospheric nitrogen into a form that can be used by the cyanobacteria and other organisms in the environment. This process is important for nitrogen cycling in ecosystems and contributes to the overall productivity of the ecosystem.
What are heterocysts?
Heterocysts are specialized cells found in certain filamentous cyanobacteria that serve as sites for nitrogen fixation. These cells create a micro-anaerobic environment, allowing nitrogenase to function effectively in converting atmospheric nitrogen into ammonia, which is essential for the organism's growth. Heterocysts are typically larger and thicker-walled than surrounding vegetative cells, and they help the cyanobacteria survive in nitrogen-poor environments. Their presence is crucial for the nitrogen cycle in aquatic ecosystems.
The nitrogen fixing Nitrogenase complex is oxygen-lible?
Nitrogenase is unable to discriminate between O2 and N2, and the O2 will degradatively oxidize the FE-S cofactors of the nitrogenase, rendering it more inefficient under increasingly aerobic conditions.
How do azotobacter make anaerobic environment for nitrogenase enzyme?
Azotobacter can create an anaerobic environment for the nitrogenase enzyme by encapsulating the enzyme in specialized structures called heterocysts, which are able to maintain low oxygen levels necessary for nitrogenase activity. Heterocysts have thickened cell walls that limit oxygen diffusion, allowing nitrogenase to function optimally under anaerobic conditions.
What is element an essential component of the enzyme nitrogenase that converts nitrogen into ammonia?
Nitrogenase contains an FE-S cluster at the active site, and most contain a molybdenum atom centered in the heterometal complex.
What is the key enzyme in nitrogen fixation?
The key enzyme in nitrogen fixation is nitrogenase. This enzyme is responsible for converting atmospheric nitrogen (N2) into ammonia (NH3), which can be used by plants and other organisms for growth and metabolism.
How anabaena solve the problem of nitrogenase not to react with oxygen?
They differentiate a select few cells into specialized semi-anaerobic nitrogen fixing cells called heterocysts.

What enzyme is involved in converting N2 to NH4 in the root nodules of legumes?
The enzyme involved in converting nitrogen gas (N2) to ammonium (NH4+) in the root nodules of legumes is nitrogenase. This enzyme catalyzes the reduction of atmospheric nitrogen, facilitating its assimilation by the plant. Nitrogenase operates in a symbiotic relationship with nitrogen-fixing bacteria, such as Rhizobium, which reside within the root nodules. The process is crucial for providing the plant with usable nitrogen, essential for its growth and development.

Which event breaks down the nitrogen in the atmosphere and converts it to a form that can be used by plants and animals?
Nitrogen fixation is how atmospheric nitrogen is processed. This occurs during lightning strikes but mainly is processed by diazotrophs, or free living bacteria with nitrogenase.
What is nitroginase?
Nitrogenase is an enzyme responsible for the biological conversion of atmospheric nitrogen gas into ammonia, which can be used by plants to synthesize essential biomolecules like proteins and nucleic acids. This process is called nitrogen fixation and is crucial for the nitrogen cycle in ecosystems.
What is the proccess by which bacteria take nitrogen out of the atmosphere?
Bacteria use an enzyme called nitrogenase to convert atmospheric nitrogen (N2) into ammonia (NH3) through a process called nitrogen fixation. This ammonia can then be used by plants and other organisms as a source of nitrogen for growth and metabolism.
What is the process by which bacteria removes nitrogen from the air and form nitrogen compounds?
Bacteria utilize an enzyme called nitrogenase to convert nitrogen gas (N2) into ammonia (NH3) in a process known as nitrogen fixation. This ammonia can then be further converted into other nitrogen compounds by bacteria to be used by plants and other organisms.
