citosolában
Cytosol is the gel-like substance that fills the interior of eukaryotic cells, excluding the organelles. It is composed of water, ions, small molecules, and large macromolecules such as proteins, nucleic acids, and carbohydrates. The cytosol plays a crucial role in various cellular processes, including metabolism, signaling, and gene expression. It serves as a medium for the transport of molecules and as a site for many enzymatic reactions. The cytosol's composition and properties can vary significantly between different cell types and under different physiological conditions. It is also a dynamic environment, with continuous turnover of its components to maintain cellular homeostasis. The cytosol is bounded by the plasma membrane on the outside and the organelle membranes on the inside, which helps to compartmentalize cellular activities and regulate the flow of molecules.
