Where would you find tubulin in a cell? list 2-3 structures.

Tubulin are the monomers of the microtubules that plays an important role in the formation of cytoskeleton. The cytoskeleton helps in providing structural framework to the cytoplasm and maintains the cell mobility.

Tubulin is numerous inside the cell. The centrosomes is the main organizing center of the microtubules that plays an important role in the cell division. The golgi bodies also constitute of the microtubules that maintain its structure. The flagella and cilia are made of tubulin that helps in the cell mobility.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
