How do bacteria breathe? Whether the bacteria are capable of respiration

Bacteria can't breathe.

Bacteria can perform respiration, and bacteria can perform aerobic respiration.

Bacteria do not have mitochondria, but they can perform aerobic respiration, which is done on the cell membrane. Such bacteria are generally aerobic or facultative anaerobes. The first stage of aerobic respiration of aerobic bacteria occurs in the cytoplasm, where pyruvate is produced into the tricarboxylic acid cycle and is thoroughly oxidized to produce CO2 and water, while releasing a large amount of energy.

Because the respiratory chain is composed on the cell membrane, the site of aerobic respiration in aerobic cells should be the cytoplasm and cell membrane.

What is anaerobic respiration.

Anaerobic respiration refers to the incomplete oxidation of organic matter by biological cells. There are no oxygen molecules involved in this process, and the incomplete oxidation products after its oxidation are mainly alcohol. In higher plants, anaerobic respiration is often called fermentation, this process has no molecular oxygen participation, and when the incomplete oxidation product after oxidation is alcohol, it is called alcoholic fermentation; If it is lactic acid, it is called lactic acid fermentation.

But in the generalized sense of "anaerobic respiration", the two concepts are usually not distinguished.

According to the different final electron acceptors, anaerobic respiration can be divided into nitrate respiration, sulfate respiration, sulfur respiration, carbonate respiration and fumarate respiration. The most typical of these is nitrate respiration.

Bacteria can respire, of course, provided that they are live bacteria.

In fact, respiration here refers to the metabolism of bacteria, and it is mainly oxidation.

The cells of the dead tree are dead and cannot respire.

Yes! There are three types of bacteria: anaerobic, aerobic, and supervisory.

1.Anaerobic bacteria live in a non-oxidizing environment and obtain energy mainly through anaerobic respiration, most of which are found in animals, mainly symbiotic organisms. For example, coliform bacteria.

2.Aerobic bacteria live in an oxidizing environment, mainly obtain energy through respiration, and are mostly found in mildew or animal and plant carcasses, such as mold and sulfur iron bacteria.

3.Facultative bacteria can live in both conditions, such as yeasts.

The survival of bacteria on the respiratory tract is affected by a variety of factors, including:

1.The immune system of the host body: Respiratory epithelial cells and immune cells are able to remove invading bacteria through various immune responses.

2.Antimicrobial resistance of bacteria: Some bacteria may have some antimicrobial resistance, which can evade the immune system of the host body and the bactericidal effect of the drug.

3.Bacterial adhesion ability: Some of the larger Xunheyun bacteria are able to adhere to the surface of respiratory epithelial cells through the surface attachment factors, thus avoiding expulsion.

4.Health status of the host body: Some factors such as fatigue, malnutrition, colds, etc., may cause the immune system of the host body to be compromised, thus increasing the chances of bacterial survival.

In general, the survival of bacteria in the respiratory tract is mainly affected by the immune system of the host body and the adaptive ability of bacteria.

1. For most organisms, the site of aerobic respiration is mitochondria.

But bacteria are prokaryotes and do not have mitochondria. So, aerobic respiration of bacteria takes place on the cell membrane of bacteria. If subdivided, the aerobic respiration of bacteria is divided into three stages. The first stage is performed in the cytoplasmic matrix, and the second and third stages are performed on the inside of the cell membrane.

2. Lactic acid bacteria are bacteria. Yeasts are fungi.

Performed in the cytoplasmic matrix.

Lactic acid bacteria are bacteria and yeast are fungi.

Cytoplasm, lactic acid bacteria are bacteria, and yeasts are fungi.

The respiration of microorganisms can be divided into three types: aerobic respiration, anaerobic respiration, and fermentation.

Aerobic respiration is one of the most prevalent and important forms of biological oxidation or productivity, with oxygen acting as the final electron acceptor.

It is characterized by the fact that after the matrix is dehydrogenated, the removed hydrogen is completed.

The entire respiratory chain is transmitted, which is eventually accepted by the exogenous oxygen molecules, producing water and releasing energy in the form of ATP.

Anaerobic respiration, also known as anaerobic respiration, refers to biological oxidation with certain inorganic oxides as hydrogen acceptors.

It is characterized by partial respiration after dehydrogenation of the matrix by conventional routes.

Chain hydrogen delivery, and finally hydrogen is received by oxidized inorganic or organic matter, and the oxidative phosphorylation capacity reaction is completed.

Fermentation has two meanings. Fermentation in a broad sense refers to any production method that uses aerobic or anaerobic microorganisms to produce useful metabolites or products such as food and beverages. Fermentation in the narrow sense refers to a kind of biological oxidation reaction in which the reducing power [h] generated by the dehydrogenation of the substrate is directly handed over to an endogenous intermediate metabolite without being transmitted by the respiratory chain under anaerobic conditions, so as to achieve the phosphorylation capacity at the substrate level.

Fermentation is not a complete oxidation and the productivity efficiency is low.

The vast majority of upper respiratory tract infections are caused by cold viruses, and common cold is caused by respiratory viruses, of which coronaviruses and rhinoviruses are the main pathogenic viruses. The clinical manifestations are characterized by nasal congestion, cough, headache, chills and fever, and general malaise. It can occur throughout the year, especially in spring.

So as long as it is caused by a cold, it is a virus. Antibiotics are not symptomatic.

There are also chronic pharyngitis infections, which are caused by bacteria. Antibiotics may be used appropriately.

In fact, it is now common for viruses and bacteria to rely on each other, and antibiotics are necessary if the antiviral drugs are not effective.
