sejtfolyadékot

Sejtfolyadék, also known as cytoplasm, is the jelly-like substance that fills a cell and surrounds its organelles. It is primarily composed of water, salts, and organic molecules. Within the cytoplasm, a complex network of protein filaments called the cytoskeleton provides structural support to the cell and is involved in cell movement and transport. The cytoplasm is the site of many crucial metabolic reactions, including glycolysis, the initial stage of cellular respiration. In eukaryotic cells, the cytoplasm is enclosed by the cell membrane, while in prokaryotic cells, it is enclosed by the cell wall. The cytoplasm's fluidity allows for the movement of substances within the cell and facilitates the interaction between different organelles. It plays a vital role in maintaining the cell's shape and internal organization.
