The cytoplasm is the cellular space between the plasma membrane and nuclear envelope. It consists of the cytosol, the cytoskeleton and organelles cell.
The cytosol (also called hyaloplasm) is the internal environment of the cytoplasm. It floats the cytoskeleton and ribosomes.
It consists of a 85% water with a high content of substances dispersed in the colloidal form (proteins, lipids, carbohydrates, nucleic acids and nucleotides and dissolved salts. Its functions include the performance, thanks to the ribosomes and protein synthesis, and amino acids dissolved in the cytosol. These proteins remain in the cytosol (enzymes, energy storage proteins or proteins that form the cytoskeleton). It produces an enormous amount of important metabolic reactions: glycolysis, gluconeogenesis, lactic fermentation, etc..
The cytoskeleton appears in all eukaryotic cells.
The chemical composition is a network of protein fibers (microfilaments, intermediate filaments and microtubules).
Its functions are to maintain cell shape, form pseudopodia, contracting muscle fibers, transporting and organizing cellular organelles.
