Mainly water-soluble small molecule organic compounds, such as glucose.

Amino acid. 2.Channel transshipment:

Refers to the facilitation of diffusion with the help of channel proteins. Classification of channels: voltage-gated channels; chemically gated channels; Mechanically gated access.

Substances transported in the channel: mainly inorganic salts.

Ionic species such as Na+, K+Factors influencing facilitated diffusion:1Concentration difference or potential difference between the two sides of the membrane.

2.Number of vectors and functional status of channels. The characteristics of facilitated transport: it needs the help of membrane proteins, does not consume the cell's own metabolic energy, and proceeds along the concentration difference.

inhibition of competitive phenomena. cell membranes and cross-arrangement modes of operation. There must be ways of competition.

There is a competitive phenomenon in the group of mineral transport methods in the play, and this is the increase in the immunity of your cells, and the immunity of this daughter-in-law increases, and the immunity of the cells.

The phenomenon of competitive inhibition in the transmaterial transport mode of the cell membrane is the inhibition of the generation of such things.

In the case of cell membranes, there is a competitive inhibition in the way substances operate, and it is supposed to be simultaneous competition.

This way of transporting matter is called osmosis.

What are the competing and inhibiting phenomena in the transport mode of chemical substances in the cell membrane? I don't know about it, and I don't understand it, so I can't get it right.

In the mode of transmaterial transport of the cell membrane, there is a competitive inhibition phenomenon that the survival of the cell reaches a minimum.

There is a competitive inhibition phenomenon in the cross-substance transport mode of the cell membrane. The main thing is that the germs and cells fight each other with an antibody.

What is the competitive inhibition of the transmaterial transport mode of the cell membrane? Well, I'll let the relevant people take a ride for us on questions like this.

The phenomenon of inhibition of transmembrane movement, and then there can only be who cares about who can not pass, which is an inhibition phenomenon.

In the way of transmembrane transport, there is a competitive inhibition, for example, if two ions can pass through a channel at the same time, then they can compete.

In the cross-substance transport mode of the cell membrane, the phenomenon of competitive inhibition is the diffusion effect of the cell membrane, and the cell membrane has a diffusion ability.

It is still difficult to achieve the cell membrane crossing the material water source.

In my words, there is a consistent phenomenon of competitive nature in the way of transporting materials, and it is controlled day by day, how come they do not have the same method as the media?

What is it that I have competitive inhibition in the transmaterial transfer relationship of the cell membrane? Its inhibition phenomenon is to indicate that its cells are divided into more water.

Phenomena exist objectively, and we should carefully analyze them with biological methods.

The modes of transport of cell membrane substances include simple diffusion, facilitated diffusion, active transport, and cell exit and cell entry.

The respective characteristics and mechanisms are:

Simple diffusion, the phenomenon in which fat-soluble small molecule substances or ions move from the high-concentration side of the membrane to the low-concentration side is called simple diffusion. The characteristics of simple diffusion are that it does not need the help of membrane proteins, does not consume the cell's own metabolic energy, and proceeds along the concentration difference, and the substances transported by simple diffusion are fat-soluble small molecules.

Facilitated diffusion refers to the transport of water-soluble small molecule substances or ions from the high-concentration side of the membrane to the low-concentration side of the membrane with the help of membrane proteins. The types of facilitated diffusion are carrier transport. Vector transport is characterized by specificity, saturation, and competitive inhibition.

Substances transported by carriers: mainly water-soluble small molecule organic substances.

Active transport refers to the transport of substances from the low-concentration side of the membrane to the high-concentration through the energy dissipation of the cell itself under the action of the biological pump on the cell membrane. The substances that are actively transported are mainly ionic substances such as sodium, potassium, calcium. It is characterized by the need for a biological pump to digest the cell's own metabolic energy, and the concentration difference is reversed.

The migration of macromolecular substances from the inside of the cell to the outside of the cell is called expulsion. The migration of macromolecular substances from the outside of the cell to the inside of the cell is called cell entry. The substances transported out and into the cell are macromolecular substances.

Exit and entry are characterized by the need for cell membrane movement, which consumes the cell's own metabolic energy.

The transport mode and characteristics of cell transmembrane substances are as follows:

First, the mode of transshipment:

1. Simple diffusion, differential concentration, no carrier, no energy.

2. Facilitation diffusion, differential concentration, need carrier, no energy, active transport, reverse concentration difference, need carrier, need energy, enter the cell: phagocytosis, swallowing, cytosis, exocytosis.

2. Features: 1. Inverse concentration gradient and inverse chemical gradient transport.

2. The energy needs to be directly supplied by ATP or coupled with the process of releasing energy, and it is sensitive to metabolic toxicity. Pei Fan Silver.

3. All have carrier proteins and depend on membrane transport proteins.

4. It is selective and specific.

Composition of the cell membrane:

It is composed of lipid bilayers, only fat-soluble substances can pass through it, and there are constantly a variety of substances, from ions and small molecules to macromolecules such as proteins, as well as clumpy solids or droplets in and out of cells, including various energy-supplying substances, raw materials for the synthesis of new cellular substances, intermediate metabolites and end products, vitamins, oxygen and carbon dioxide, as well as Na+, K+, Ca2+ ions, etc., their physical and chemical properties are different, and most of them are insoluble in lipids or their water solubility is greater than their fat solubility.

There are five forms of transmembrane material transport in the cell membrane: x0d (1) simple diffusion: transmembrane transport of fat-soluble substances such as O2, CO2, NH3, etc.; x0d(ii) Facilitation diffusion:

It is further divided into two types:1Carrier-mediated facilitated diffusion, e.g., glucose from the blood into red blood cells; 2.

Channel-mediated facilitation.

1. Free diffusion.

The diffusion of a substance from the high-concentration side through the plasma membrane to the low-concentration side does not require a carrier and does not consume energy. The free diffusion rate of a substance is related to the degree of fat solubility of the substance, the difference in solute concentration between the two sides of the membrane, the size of the solute molecule and the properties of the charge.

2. Assist in diffusion.

The substance must be assisted by a carrier protein in order to diffuse from the high-concentration side through the plasma membrane to the low-concentration side, but this method does not consume metabolic energy.

3. Active transportation.

It is the way in which carrier proteins on the plasma membrane consume energy and assist in the transport of substances against the concentration gradient. Substances are transported against the concentration gradient with the assistance of carrier proteins, which consume the energy provided by ATP.

4. Cytocytosis.

The transport of biological macromolecules and particulate matter inside and outside the cell is completed through a series of processes such as membrane bubble formation, displacement, and fusion, so it is called membrane bubble transport, which does not require the assistance of carrier proteins in the transport process, but needs to consume cellular metabolic energy. According to the direction of transport, it can be divided into two ways: endocytosis and exocytosis.

5. Through-cell transportation.

A pinocytotic vesicle is formed on one side of the cell to cross the cytoplasm and the other side releases the material in the vesicle.

6. Intracellular membrane vesicle transport.

The transport of substances between the various parts of the intracellular membrane system also takes place through the membrane vesicle transport mode.

There are four modes of cell transmembrane material transport: from the perspective of energy consumption, it can be divided into active transport and passive transport.

Free diffusion: refers to the diffusion process of fat-soluble small molecules through the cell membrane along the concentration difference. (Passive).

Transport: CO2, O2, N2, ethanol, urea, etc.

Characteristics: High concentration Low concentration.

No energy consumption. Assisted diffusion: refers to the diffusion of some non-fat-soluble or small fat-soluble small molecule substances from the high-concentration side to the low-concentration side with the help of carrier proteins and channel proteins on the membrane. (Passive).

Characteristics: High concentration Low concentration.

No energy required. Selective.

Permeability can be changed.

Active transport (or active transport): It is the transmembrane transport process in which cells transport substances against a concentration gradient or potential gradient through an energy-consuming process.

Features: High concentration, low concentration, inverse concentration gradient (inverse chemical gradient) transport;

requires energy (directly powered by ATP) or is coupled to a process that releases energy (co-transport) and is sensitive to metabolic toxicity;

all have carrier proteins and are dependent on membrane transport proteins;

Selective and specific.

Membrane vesicle transport (exit and entry): Exit refers to the process by which macromolecular substances in the cytoplasm are expelled from the cell in the form of secretory vesicles. Endocytosis refers to the process by which macromolecular substances or clumps of substances (such as bacteria, viruses, foreign substances, lipids, etc.) enter the cell.

Features: Directional transshipment.

Energy is needed. Depends on a variety of proteins and coupling mechanisms.

It can transport macromolecular substances.

Answer]: Transmembrane diffusion of CNA along the concentration gradient or propotential ladder is channel-facilitated diffusion. The sodium pump moves the intracellular NA out of the cell, which is carried out against the concentration difference, which is a primary active transport.

Excellularity and dispersion or entry into the cell is a way in which macromolecular substances or mass clumps of substances complete transmembrane transport with the help of the movement of the cell membrane.
