What are the differences between cytosol and cytoplasm?
Posted June 16, 2022
The terms cytosol and cytoplasm are often used interchangeably. However, they are two distinctly different terms. Here’s a look at the differences between cytosol and cytoplasm.
|Basis of Differentiation||Cytosol||Cytoplasm|
|Definition||Is the liquid component of the cytoplasm surrounded by the cell membrane||Is the gel-like viscous cell component that’s surrounded by the cell membrane including the liquid within organelles|
|Composition||Composed of water, soluble ions, large and small water-soluble proteins, and molecules||water, nucleic acids, enzymes, and amino acids|
|Diversity||Low diversity - consists largely of water with a few cell components suspended within it||High diversity - consists of the cytosol and all the other cell components with the exception of the nucleus|
|Components||Components include water, soluable small and large molecules.||Components include cytosol, organelles such as mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and insoluble cytoplasmic inclusions such as calcium oxalate, lipid droplets, and glycogen.|
|Metabolism||All chemical reactions take place here (for prokaryotes)||Involved in large cellular metabolic activities such as glycolysis and cell division.|
|Activities||Is the site in the cell where transportation of molecules and signal transduction occurs.||Is the site in the cell where cytokinesis, nuclear division, and signal transduction occurs.|
|Functions||Concentrates its dissolved molecules into the precise positions to facilitate efficient metabolism||Freezes organelles in place to facilitate efficient metabolism.|
