The main site of cell metabolism in the body is the cytoplasmic matrix. It is the main place for cell metabolism, and various biochemical reactions are completed in the cytoplasmic matrix. The part of the cytoplasm inside the cell membrane and outside the nucleus. The state of constant flow outside the cytoplasm of a living cell. Cytoplasm includes cytoplasmic matrix and various organelles. In the cytoplasmic matrix, it contains water, inorganic salt ions, lipid sugars, amino acids and nucleotides, as well as many enzymes. Cytoplasmic matrix is the main place for metabolism of living cells. Cytoplasmic matrix provides necessary substances and certain environmental conditions for metabolism. 1, the cytoplasmic matrix is the main place of metabolism of living cells, which provides the necessary substances for metabolism, such as enzymes. 2. The cytoplasmic matrix provides a stable microenvironment for organelles. 3. Cytoplasmic matrix affects cell shape. 2, the structure of the cytoplasmic matrix: 1, macromolecular substances: proteins, lipoproteins, polysaccharides, RNA. 2, medium molecules: amino acids, nucleotides, lipids. 3, small molecular substances: water, inorganic ions (Na+, K+, etc.).
