WebMay 1, 2024 · Gaseous nitrogen is diatomic, meaning that it is a two-atom molecule. That form of nitrogen has the two atoms held together by a triple bond. For that reason, N 2 represents a very stable molecule, and splitting it requires a considerable amount of energy (946 kJ/mol). It is this splitting of a strong bond which is a condition for nitrogen fixation.

Oxygen effect - Wikipedia

Oxygen cycle refers to the movement of oxygen through the atmosphere (air), biosphere (plants and animals) and the lithosphere (the Earth’s crust). The oxygen cycle demonstrates how free oxygen is made available in each of these regions, as well as how it is used. The oxygen cycle is the biogeochemical cycle of oxygen atoms between different oxidation states in ions, oxides, and molecules WebIt catalyses the first step of carbon fixation in the C3 pathway or Calvin cycle, i.e. carboxylation of RuBP. It results in the formation of 2 molecules of 3-PGA.
