Citosoliche

Citosoliche is a term that refers to the cytosol, which is the aqueous component of the cytoplasm of a cell, within which various organelles and particles are suspended. It comprises the gel-like substance that fills the cell and surrounds the organelles. The cytosol itself is primarily composed of water, but also contains dissolved ions, small molecules, and soluble macromolecules such as proteins.

Within the cytosol, numerous essential biochemical reactions take place. These include glycolysis, the initial stage of cellular respiration, where glucose is broken down into pyruvate. Other metabolic pathways, such as protein synthesis on free ribosomes and various signaling cascades, also occur in the cytosol. The cytosol's composition and dynamic nature are crucial for maintaining cellular function and responding to environmental changes.

The distinction between cytosol and cytoplasm is important. Cytoplasm encompasses both the cytosol and the organelles suspended within it, excluding the nucleus. Therefore, cytosol refers specifically to the fluid portion of the cytoplasm. The cytosol provides the medium for the movement of molecules within the cell and plays a vital role in maintaining cell shape and facilitating intracellular transport.
