How long does it take for cells to die after anaerobic respiration?

Oh, the landlord is too worried, if it is a person, when exercising vigorously, the cells generally do not carry out anaerobic respiration all the time.

However, it does not mean that all cells are respiring without oxygen, nor is it that a cell is constantly respiring without oxygen, and the body will regulate, so that the possibility of cells dying due to prolonged anaerobic respiration is almost zero.

Of course, prolonged strenuous exercise can lead to damage to muscle cells and death (such as muscle strain, etc.).

Also, if cells leave the body, or if the body is unable to supply oxygen to the cells, the cells may die due to lack of oxygen.

For example, there is a time requirement for reconnection after the finger is severed, and generally speaking, under the protection of ice cubes, cellular respiration is the weakest, and it can be separated from the body for about 12 hours; If the room temperature is 6-7 hours.

In the same way, if you are bitten by a snake, in order to break the snake venom, you should also relax for 1 minute every 15 minutes to avoid hypoxia and necrosis of the body.

You're giving an example of muscle cells.

For the individual itself, five minutes of lack of oxygen can cause irreparable damage to the brain, and ten minutes of death.

Muscle soreness after running is caused by muscle cells producing lactic acid, which is converted by the liver. Don't worry too much.

The hazards of anaerobic respiration for anaerobic respiration are not dead, and the harm of anaerobic respiration for anaerobic respiration is that the organism needs a large amount of energy is not sufficiently supplied, and the second is that anaerobic respiration produces the accumulation of alcohol (plants) or lactic acid (animals), which is toxic to the organism. How long it takes to die depends on the growth of the subject.

Anaerobic respiration.

The fermentation process anaerobic respiration is a form of cellular respiration.

According to the different classification methods of the final electron acceptor, cellular respiration is divided into three types: fermentation, aerobic respiration, and anaerobic respiration. Yeast brewing, homolactic acid fermentation, and heterolactic acid fermentation all belong to the category of fermentation, rather than anaerobic respiration. To put it simply, it is not anaerobic respiration that does not utilize oxidation using molecular oxygen.

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

Fermentation is often referred to as anaerobic respiration in microorganisms, which refers to the incomplete oxidation of organic matter by living cells. There is no molecular oxygen involved in this process. When the incomplete oxidation product after oxidation is alcohol, it is called alcohol fermentation, and the total reaction formula:

c6h12o6→2c2h5oh+2co2↑+2atp；If it is lactic acid, it is called lactic acid fermentation, and the total reaction formula is: C6H12O6 2C3H6O3+2ATP.

Under hypoxic conditions, only anaerobic respiration can be carried out to temporarily maintain its vital activities. Anaerobic respiration can eventually cause harm to plants, which may be due to the incomplete oxidation of organic matter and the production of less energy. Thus, due to the Pasteur effect, the rate of glycolysis is accelerated to compensate for the low ATP yield.

This will lead to the accumulation of incomplete oxidation products, which will be toxic to cells; In addition, it also accelerates the consumption of sugar, and there is a danger of depleting the respiratory substrate.

Anaerobic Respiration Formula:

Alcoholic fermentation: C6H12O6 2C2H5OH + 2CO2 + energy.

Arrow superscript: enzyme, this reaction occurs mainly in plants).

Malolactic fermentation: C6H12O6 2C3H6O3 + energy.

Arrow superscript: enzyme, this reaction occurs mainly in animals, but not absolutely, such as potato tubers and sugar beet tubers).

The whole process of anaerobic respiration.

The first stage: in the matrix of the cytoplasm, it is exactly the same as the first stage of aerobic respiration. That is, one molecule of glucose is broken down into two molecules of pyruvate, and a small amount of [H] and a small amount of energy are released in the process.

Stage 2: In the cytoplasmic matrix, pyruvate is catalyzed by different enzymes to break down into alcohol and carbon dioxide, or converted into lactic acid.

It is important to note that the conversion of pyruvate to alcohol or lactic acid does not produce energy.

Anaerobic respiration. It refers to the complete or incomplete oxidation of organic carbon compounds, and the electrons removed are transferred to exogenous inorganic oxides (some organic oxides) through part of the electron transport chain and release less energy.

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.

Anaerobic respiration is not completely broken down, and some of the energy is stored in alcohol or lactic acid1

After mol glucose is decomposed into lactic acid, only 61 08kJ of energy is stored in ATP, and nearly 69% of the energy is lost in the form of heat energy

Cellular respiration, aerobic respiration, and anaerobic respiration.

Aerobic respiration is the process in which cells completely oxidize and decompose organic matter to produce carbon dioxide and water with the participation of oxygen, and at the same time release a large amount of energy.

Anaerobic respiration is the process of generating alcohol and carbon dioxide and releasing a small amount of energy without the need for oxygen in the cells, and the process of generating alcohol and carbon dioxide and releasing a small amount of energy.

When does cellular respiration consume the least amount of oxygen and why.

Photosynthesis produces a certain oxygen molecule that enters the adjacent mesophyll cells to participate in cellular respiration, at least through 14 layers of phospholipid molecules.

Oxygen comes out of the capsule and passes through 1 membrane;

Then the chloroplast is passed through 2 layers of membrane;

Penetrate the cell through 1 layer of membrane;

Adjacent cells enter the sedan car and pass through 1 layer of membrane;

Enter the mitochondria and cross the 2 layers of membrane.

There are 7 biofilms, that is, 14 layers of phospholipid molecules.
