What would a lifeform that carried nitrogen in blood instead of oxygen be like?
Katamari said:Okay then, different question. Is there any chemical group (Amines, nitrophenols, fluorocarbons etc) that acts as an effective oxidiser and will react in sunlight, forcing these hypothetical creatures to be nocturnal.
Nitrogen respiration is a process by which living organisms use nitrogen as an energy source. It involves the breakdown of nitrogen-containing compounds, such as amino acids, to release energy for cellular processes.
Many types of bacteria, archaea, and fungi have the ability to respire using nitrogen. Some plants and animals, such as legumes and termites, also have symbiotic relationships with nitrogen-fixing bacteria that allow them to use nitrogen for respiration.
Oxygen respiration is the most common form of respiration in living organisms and involves the use of oxygen to break down organic compounds for energy. Nitrogen respiration, on the other hand, uses nitrogen-containing compounds as an energy source and does not require oxygen.
Nitrogen respiration allows organisms to use a wider range of nitrogen-containing compounds as an energy source, which can be advantageous in environments with limited oxygen or scarce organic molecules.
Nitrogen respiration can be a slower process compared to oxygen respiration, which may limit the growth and reproduction of organisms that rely on it. Additionally, the byproducts of nitrogen respiration, such as ammonia, can be toxic in high concentrations.
