How much energy is produced in each of the three phases of aerobic respiration

Aerobic respiration is divided into three phases:

The first stage: in the matrix of the cytoplasm, it is called glycolysis.

Reaction formula: C6H12O6 enzyme 2C3H4O3 (pyruvate.

4[h] + a small amount of energy.

2ATP) Phase II:

Pyruvate enters the mitochondria.

of the matrix. This stage also does not require the involvement of oxygen and is carried out in the ** stroma. Reaction formula: 2C3H4O3 (pyruvate) + 6H2O enzyme 20[H] + 6CO2 + small amount of energy.

2ATP) Phase III:

** On the inner membrane of the chondria, a large amount of energy is produced. This phase requires the involvement of oxygen and is carried out on the inner membrane of the first chondrium. Reaction formula: 24[H]+6O2 enzyme 12H2O+ large amount of energy (34ATP).

The first stage: in the cytoplasmic matrix, this stage does not require the involvement of oxygen and is carried out in the cytoplasmic matrix. Reaction formula: C6H12O6 enzyme 2C3H4O3 (pyruvate) + 4 [H] + a small amount of energy.

2ATP) Phase II:

Pyruvate enters the mitochondrial matrix, which does not require the participation of oxygen at this stage and is carried out in the ** chondrial matrix. Reaction formula: 2C3H4O3 (pyruvate) + 6H2O enzyme 20[H] + 6CO2 + small amount of energy.

2ATP) Phase III:

On the inner membrane of the chondria, this phase requires the participation of oxygen and is carried out on the inner membrane of the chondria. Reaction formula: 24[H]+6O2 enzyme 12H2O+ large amount of energy (34ATP).

Compared with aerobic respiration, anaerobic respiration has incomplete oxidative decomposition of substances and less energy release.

On the premise of **, aerobic exercise is more helpful for fat burning, and if it is plastic, anaerobic exercise has obvious effects.

Summary. Hello, the three phases of aerobic respiration produce energy of 2ATP, 2ATP, and 34ATP respectively.

The first stage: the production of a small amount of energy, that is, the energy that produces 2ATP, occurs in the cytoplasmic matrix, this stage does not require the participation of oxygen, it is carried out in the cytoplasmic matrix.

The second stage: to produce a small amount of energy, that is, to produce 2ATP energy, pyruvate into the mitochondrial matrix, this stage also does not require the participation of oxygen, is carried out in the ** chondrial matrix.

ok thanks. You're welcome oh can I give a thumbs up if mine is helpful to you, thank you.

1 1 The statement of the new curriculum standard textbook: the second stage of anaerobic respiration is not discharged.

The whole process of anaerobic respiration can be broadly divided into two stages, which require the catalysis of different enzymes, but both are carried out in the cytoplasmic matrix.

The first stage is exactly the same as the first stage of aerobic respiration.

In the second stage, pyruvate is catalyzed by different enzymes and decomposes into alcohol and carbon dioxide.

or converted to lactic acid.

Whether it is broken down into alcohol and carbon dioxide or converted into lactic acid, anaerobic respiration releases only a small amount of energy in the first stage, producing a small amount of ATPGlucose.

Most of the energy in the molecule is retained in alcohol or lactic acid.

2 The old textbook says: This issue is not clear.

3 Whether the second stage of anaerobic respiration is releasing or not.

Actually, the second stage of anaerobic respiration is the process in yeast.

As with most plant tissues, pyruvate is first decarboxylated to form acetaldehyde.

Acetaldehyde is then reduced to ethanol by Nadh+H+ (abbreviated as [H]) formed in the first stage.

In human or animal tissues, the second stage of anaerobic respiration is the reduction of pyruvate to lactate by NADH+H+ (abbreviated as [H] in secondary school textbooks) formed in the first stage.

As you know, energy is released during the oxidation of organic matter, and energy is stored in the process of organic matter reduction. In this way, the second stage of anaerobic respiration not only does not release energy, but also stores energy, which is the energy released in the first stage of anaerobic respiration and stored in NADH+H+ (abbreviated as [H]) in secondary school textbooks.

The process of aerobic respiration can be divided into three stages, the first stage: glucose.

Preliminary decomposition. From the perspective of material changes: first, glucose is broken down into pyruvate.

Second, a small amount of [h].] is producedIn terms of energy changes, due to the initial decomposition of glucose, a small amount of energy is released, and a small amount of ATP is formedAs we can see from the diagram, the first stage is not ** chondria.

but in the cytoplasmic matrix.

Stage 2: Complete decomposition of pyruvate. In terms of material change:

First, pyruvate decomposes to produce CO2; second, to remove the remaining hydrogen at the same time; From the perspective of energy change, a small amount of energy is released to form a small amount of ATPThis step occurs in the stroma of the stroma of the stroma because there are a large number of enzymes involved in the matrix.

The third stage: on the one hand, the [h] taken off in the first two stages is combined with oxygen to form water through a series of material transfers; On the other hand, in the process of hydrogen transfer, a large amount of ATP is formed. This stage is the most productive and requires the catalytic folding of many enzymes in the inner mitochondrial membrane to expand the area to which these enzymes are attached, so that at the enzyme concentration, the basal particles are formed.

Anaerobic respiration. The whole process can be divided into two stages. The first stage is the same as the first stage of aerobic respiration, and the second stage has two different conditions, one is that pyruvate removes a CO2 under the action of certain enzymes, and then combines with the [H] taken off in the first stage to form alcohol, and produces a small amount of energy; The other is that in some plants, due to the different enzymes in the cells, pyruvate directly combines with the [H] taken off in the first stage to form lactic acid.

such as the embryo of corn, the tuber of potato, etc.), and produce a small amount of energy. The site where anaerobic respiration takes place is the cytoplasmic matrix.
