Cytoplasm contains a lot of things. The main components of cytoplasm are ribosomes, reservoirs, a variety of enzymes and intermediate metabolites, plasmids, monomers of various nutrients and macromolecules, etc., and a few bacteria also have thylakoids, carboxysomes, bubbles or concomitant spore crystals. It is the main site of metabolism, and the vast majority of chemical reactions take place in the cytoplasm.

At the same time, it also has a regulatory effect on the nucleus.

It provides nutrients and energy to the nucleus, and the cytoplasmic matrix is the main site of metabolism, in which a variety of organelles with certain structures and specific functions are suspended.

Cytoplasm includes cytoplasmic matrix and organelles.

The cytoplasmic matrix is the center of cellular metabolism, and most chemical reactions take place in the cytoplasmic matrix.

Organelles, intracellular division of labor and cooperation. Complete a variety of life activities of cells.

Maintaining a stable internal environment is the site of a lot of reactions, maintaining cell shape, maintaining cell expansion and osmotic pressure, thank you.

The cytoplasm presents a viscous, light-colored substance, which is mainly the main site of cell metabolism.

The cytoplasm is the main site of metabolism, and the vast majority of chemical reactions take place in the cytoplasm. At the same time, it also has a regulatory effect on the nucleus.

Cytoplasm is a general term for all translucent, gelatinous, and granular substances surrounded by the cytoplasmic membrane except for the nuclear region. The main components of cytoplasm are ribosomes, reservoirs, a variety of enzymes and intermediate metabolites, monomers of various nutrients and macromolecules, etc., and a few bacteria also have thylakoids, carboxysomes, bubbles or conesporous crystals.

Cytoplasm is composed of cytoplasmic matrix, endomembrane system, cytoskeleton and inclusions, cytoplasm is the main site of metabolism, and most of the chemical reactions are carried out in the cytoplasm. At the same time, it also has a regulatory effect on the nucleus.

The part within the cytoplasmic membrane and outside the nucleus. It is composed of homogeneous translucent cytosol and organelles and inclusions. Cytosol occupies about 1 2 cell volume and contains inorganic ions (such as K+, Mg2+, Ca2+, etc.), lipids, sugars, amino acids, proteins, etc.

Backbone proteins are closely related to cell morphology and motility and are thought to provide a favorable framework structure for enzymatic reactions in the cytosol. Most of the intermediate metabolism of substances and the modification of some proteins are carried out in the cytosol. The organelles suspended in the cytosol, both with and without boundary, are involved in a variety of metabolic pathways of the cell.

Endocannabinoids are products formed during the metabolism of cellular life, such as glycogen, pigment granules, fat droplets, etc.

1 Basic composition of the cytoplasmic matrix.

The cytoplasmic matrix is mainly composed of water (about 70%), protein (about 20% 30%) and a few inorganic ions (such as Na+, K+, Cl). Water molecules exist in the cytoplasmic matrix in two forms: free (about 5%) and chemical (about 95%). Among them, the free water molecules act as solvents, and the chemical water molecules bind to the surface of macromolecules such as proteins.

Most of the proteins synthesized in the cytoplasmic matrix are transported to the nucleus and various organelles, and participate in the material transport, energy flow, and information exchange of various metabolic reactions of the cell. It has been found that most proteins in the cytoplasmic matrix, including soluble proteins, exist in a bound form that binds to biological membranes or cytoplasmic backbones to complete a variety of complex biological functions. The inorganic ions in the cytoplasmic matrix maintain the pH within the cell.

2. Function of the cytoplasmic matrix.

Many intermediate metabolic processes within the cell occur in the cytoplasmic matrix, such as glycogen synthesis and decomposition, glycolysis, etc. This is because there are enzymes in the cytoplasmic matrix that catalyze a variety of metabolic reactions, which change their own kinetic parameters by binding to the cytoplasmic skeleton to improve the catalytic efficiency, and can also polymerize with related enzymes into complexes to target specific sites in the cytoplasmic matrix to complete complex metabolic reactions.

Role of cytoplasm:

1. Provide a place for metabolism: Since the main components of cytoplasm, cytosol, organelles and endocannabinoids, the proteins that make up the cytoplasmic skeleton provide a place for the reaction of intracellular enzymes. The potassium, calcium, and magnesium ions inside can also provide the ionic environment required for chemical reactions.

2. Regulation of the nucleus: The nucleus is surrounded by the cytoplasm of the dust, and the substances required for the metabolism of substances in the nucleus need to be provided by the cytoplasm.

3. Cellular inclusions play a role in storage: they play an important role in the formation of posterior generae such as flagella and cilia and the storage of cellular inclusions. For example, most proteins, fat particles, glycogen, and alkaloids are concentrated in the cytoplasm.

The cytoplasm is composed of the cytoplasmic matrix, the endomembrane system, the cytoskeleton and the inclusions, and is the main place for the Meditation movement. The cytoplasm includes the matrix, organelles, and inclusions, and is a transparent gelatinous substance in the living state. Matrix refers to the liquid part of the cytoplasm, which is the basic component of the cytoplasm and mainly contains a variety of soluble enzymes, sugars, inorganic salts and water.

Organelles are structures that are distributed in the cytoplasm, have a certain morphology, and play an important role in cell physiological activities. It includes: mitochondria, chloroplasts, plastides, endoplasmic reticulum, Golgi apparatus, vacuolar system (lysosomes, vacuoles), cytoskeleton (microfilaments, microtubules, intermediate fibers), centrioles, and surrounding substances.
