What organisms can change nitrogen gas into ammonia?
These enzymes are called nitrogenases.
Why is converting atmospheric nitrogen to ammonia important to pants and animals?
Plants need nitrogen to make DNA and amino acids. Amino acids are used to make proteins, including enzymes, which are needed for some vital reactions, such as photosynthesis and respiration to happen. Plants can't make use of the nitrogen in the air because it is too unreactive. However, they can absorb and use nitrate ions dissolved in water, which are made from ammonia by nitrifying bacteria in the soil.
Why cannot green plants absorve gasious nitrogen?
green plants do not have the "power" to break the triple bond of N2 molecule. in better words, they do not have suitable enzymes. on the other hand, some bacteria have, the so colled "nitrogen fixing bacteria", living on legume plant roots.
Enzymes that open the double helix by breaking hydrogen bonds between nitrogen bases is what?
Helicase.
Why are nitrates used to help preserved food?
The ion nitrate used in curing is converted to nitrite by enzymes or bacteria. The nitrite then prevents the bacteria from growing.
What organisms can change nitrogen gas into ammonia?
These enzymes are called nitrogenases.
What do ammonia urea and enzymes have in common?
nitrogen
Cyanobacteria are able to fix nitrogen gas into ammonia because they have?
Heterocysts containing enzymes.
How can microorganisms enhance plant growth?
Plants need nitrogen. Unfortunately, gaseous nitrogen from the air is triple bonded and entering the soil thus make it unusable to plants because they have not way to break the triple bonds. There is a bacteria in a mutalistic, symbiotic relationship with plants and this bacteria has the proper enzymes to fix nitrogen into usable forms such as ammonia.
What can you infer from the fact that animals do not need nitrogen?
If you are told it is a fact that animals do not need nitrogen, you can infer that you are receiving incorrect information. All living things require nitrogen. However, animals are not able to obtain the nitrogen they need directly, but must get it from their food, and that comes ultimately from the plants that are able to absorb nitrogen from the soil.
What occurs during nitrification?
Step 1: Nitrogen-fixation Atmospheric: Happens when Nitrogen (N2) is oxidized at high temperatures (by lightning, in internal combustion engines) to make nitrite (NO2). This can combine with water to form nitric acid (H2NO3), which is deposited on earth through rainfall. Biological: Done by bacteria which can convert N2 into ammonia (NH3) if an energy source is present. Some get this energy by directly absorbing sunlight (blue-green algae) or by living in the roots of plants (legumes, alder trees), who provide them with food (Rhizobium, Azospirillium). Step 2: Conversion to Ammonia. As amino acids and nucleic acids require N in the form of Ammonia, if nitrate (NO3) present, it must be converted to NH3. This is done through Nitrate reductase enzymes. Step 3: Biological Use. Ammonia is incorporated into proteins, nucleic acids Step 4: When organism dies, ammonia is relased back into the biosphere through the process of Ammonification, in which water is added to proteins to make carbon dioxide and ammonia. This process happens during digestion, and is also done by bacterial and fungal decomposers. Step 5: If ammonia released into oxygen rich (anerobic) soil, other bacteria can convert it into nitrite or nitrate through the process of Nitrification: NH4+ + 2O2 = NO3- + H2O + 2H. This is a problem, as it gives the molecule which contains Nitrogen a negative charge, which repels it from soil particles, causing it to be easily leached into streams and groundwater. Step 6: If soils remain anerobic, another group of poop will convert it back into inert, atmospheric N2 through the process of Denitrification. In this process, bacteria use nitrate as an Oxygen source for respiration: C6H12O6 + 4NO3- = 6CO2 + 6H2O + 2N2 AND THE SPACE UNICORN WILL SAVE US ALL!! XD

What does ammonia do to things?
Ammonia will denature enzymes.
Why cant plants absorb gaseous nitrogen?
plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.
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
How do plants get nitrogen from the atmosphere?
Direct nitrogen fixation is performed by a rather specific kind of organism that probably lived free before the atmosphere began to contain oxygen. Today these are anaerobic bacteria that live in nodules on the roots of plants, particularly the legumes. The actual process is brought about by enzymes called nitrogenases. It is an energy intensive process, requiring a lot of ATP in acid conditions. To fix one molecule of nitrogen requires sixteen ATP molecules and the product is ammonia, which is immediately converted to ammonium ion by acid hydrogen. This is still not available to the plant, but if excreted into the soil other aerobic bacteria convert it to nitrite using oxygen, and then nitrate, and this is available to the plant. Another pathway is to convert the ammonium directly into glutamic acid, which the plant can use directly to generate protein.
Helicobacter pylori bacteria grow in the human stomach These bacteria produce a large amount of urease Of what value is this urease to Helicobacter?
Urease enzymes are responsible for the conversion of ammonia to carbon dioxide. It is said to be beneficial to the bacteria because it neutralizes the acidity in the stomach.
