Bacteria with the ability to perform nitrogen fixation, such as Rhizobium and Azotobacter, have an enzyme called nitrogenase that enables them to convert atmospheric nitrogen gas (N2) into ammonia (NH3). This process is essential for making nitrogen available to plants for growth and survival.
The bicarbonate buffer system plays a role in anaerobic activity by maintaining the pH and electrolyte levels in the body. This can help reduce fatigue and enhance performance during activities that require a high energy rate.
nitrogen fixation is caused by the bacteria called rhizobium.
An enzyme that works best in an acidic environment would function best at a pH below 7, typically around pH 4 to 6. At this pH range, the enzyme's active site is more stable and optimal for catalyzing reactions.
Pepsinogen is activated in the stomach by the acidic environment, which triggers a change in its structure to become the active enzyme pepsin.
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.
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.
Nitrogenase contains an FE-S cluster at the active site, and most contain a molybdenum atom centered in the heterometal complex.
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
Bacteria with the ability to perform nitrogen fixation, such as Rhizobium and Azotobacter, have an enzyme called nitrogenase that enables them to convert atmospheric nitrogen gas (N2) into ammonia (NH3). This process is essential for making nitrogen available to plants for growth and survival.
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.
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.
Anaerobic enzymes are those that function in the absence of oxygen. They help facilitate metabolic processes in environments where oxygen is limited or absent, such as during anaerobic respiration in cells. These enzymes are crucial for generating energy and carrying out essential chemical reactions without relying on oxygen as an electron acceptor.
Enzyme activity is affected by other molecules, temperature, chemical environment (e.g., pH), and the concentration of substrate and enzyme. Activators are molecules that encourage enzyme activity, and inhibitors are enzymes that decrease enzyme activity. Sometimes a cofactor is necessary for the enzyme to work.
No, anaerobic bacteria do not require oxidase because they do not use oxygen for their metabolism. Oxidase is an enzyme used by aerobic bacteria to catalyze the transfer of electrons to oxygen during respiration. Anaerobic bacteria have alternative pathways for energy generation in the absence of oxygen.
H2SO4 is used to denature the enzyme and stop the reaction instantly. by adding H2SO4,it will prevent further reaction of the enzyme onto the substrate and the rate of enzyme reaction can be measured in the specific time
Fermentation is the breakdown of carbohydrates by enzyme action under anaerobic conditions. This is important to provide energy when insufficient oxygen is present.
