What are the substances that can be produced during both aerobic and anaerobic respiration?

Aerobic respiration C6H12O6 + 6O2 + 6H20 6 CO2 + 12H2O+ energy.

Anaerobic respiration C6H12O6 2C2H5OH + 2CO2 + energy.

At first glance, you can't choose it, but the answer is A

ATP is the abbreviation of adenosine triphosphate, and its structural formula is: a—p p p It is an organic compound containing high-energy phosphate bonds, and a large amount of its chemical energy is stored in high-energy phosphate bonds.

ATP is a direct form of energy for vital activities, but it is not high in the body.

The ATP energy stored in the human body can only last for 15 seconds, and it will be used up after running 100 meters, and the insufficient ATP will continue to be synthesized through respiration.

is the substance, adenosine triphosphate;

Both aerobic and anaerobic respiration produce ATP and reduced hydrogen.

Aerobic respiration: glycolysis produces NADH and ATP, KREBS cycle produces NADH, FADH2, ATP and water, oxidative phosphorylation produces ATP and water;

Anaerobic respiration: glycolysis produces NADH and ATP, and NADH reduces pyruvate to produce lactic acid (or carbon dioxide and ethanol); Anaerobic respiration does not produce water.

To sum up, choose ab.

Aerobic respiration produces water and carbon dioxide, and anaerobic respiration produces carbon dioxide and alcohol.

Glucose undergoes a slow oxidation reaction under the action of enzymes Equation:

Aerobic respiration refers to the process in which cells completely oxidize and decompose organic matter (usually mainly decomposing glucose) through the catalytic action of a variety of enzymes with the participation of oxygen, produce carbon dioxide and water, release energy, and synthesize a large amount of ATP.

Aerobic respiration is the main form of respiration in higher animals and plants, and the so-called respiration usually refers to aerobic respiration. Aerobic respiration takes place in the cytoplasmic matrix and mitochondria, and mitochondria are the main sites for cells to perform aerobic respiration.

Anaerobic respiration is glycolysis, the product is pyruvate and NADH, ATP, pyruvate can be converted into lactic acid or ethanol, etc., aerobic respiration is pyruvate further decomposition, the product is carbon dioxide, water, ATP, etc.

The first stage of aerobic respiration: 1 molecule of glucose is decomposed into 2 molecules of pyruvate, a small amount of [H] is produced, and a small amount of energy is released, and the rest is lost as heat energy. This stage does not require the involvement of oxygen and is carried out in the cytoplasmic matrix.

Aerobic respiration stage 2: pyruvate and water are completely broken down into carbon dioxide and [h] and a small amount of energy is released. This phase does not require the involvement of oxygen and is carried out in the ** stroma and on the mitochondrial crest.

The third stage of aerobic respiration: The [h] produced by the above two phases, after a series of chemical reactions, combines with oxygen to form water, and at the same time releases a large amount of energy. This phase requires the involvement of oxygen and is carried out on the inner membrane of the first chondrium.

The equation for the first stage of anaerobic respiration is C6H12O6 + enzymatic reaction to produce 2C3H4O3 + 4H + 2ATP (a small amount). The second stage equation is 2C3H4O3 + 4H+ enzyme reaction to produce 2C3H6O3 (lactate) + energy (a small amount).

The first stage is in the matrix of the cytoplasm and 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 under the action of enzymes, releasing a small amount of h] and a small amount of energy in the process.

In the second stage, in the cytoplasmic matrix, pyruvate is catalyzed by different enzymes and decomposed into alcohol and carbon dioxide, or converted into lactic acid. It is important to note that in the high school years, the second stage of anaerobic respiration of the cells does not produce energy.

Characteristics of anaerobic respiration.

Anaerobic respiration is characterized by the dehydrogenation of the substrate according to the conventional route, which is transmitted through part of the respiratory chain, and finally receives hydrogen by the inorganic or organic matter in the oxidized state, and completes the capacity reaction of oxidative phosphorylation. Anaerobic respiration is less productive than aerobic respiration, but much greater than fermentation alone. The vast majority of microorganisms that undergo anaerobic respiration are bacteria.

Anaerobic respiration can be classified into various types according to the hydrogen (electron) acceptor at the end of the respiratory chain.

The process of aerobic respiration can be divided into three stages, the first stage: the initial breakdown of glucose. In terms of material change:

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 carried out in the ** chondria, but in the matrix of the cytoplasm.

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 into water by a series of substances through a series of substances and oxygen cultivation; 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.

The whole process of anaerobic respiration 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 state embryo of corn, the tuber of potato, etc.), and produces a small amount of energy. The site where anaerobic respiration takes place is the cytoplasmic matrix.

1. Because alcohol and lactic acid, the products of anaerobic respiration.

It is still organic matter, and alcohol and lactic acid still contain energy that is not completely released, so the anaerobic respiration product is an incomplete oxidation product.

2. Aerobic respiration is the complete decomposition of organic matter into water and carbon dioxide.

These inorganic substances, so the energy is completely released, so the energy released by anaerobic respiration is less than that of aerobic respiration.

3. The respiration is divided into two links, the first part is glycolysis, glucose is decomposed into pyruvate through glycolysis, and there are not many broken bonds in this process, so there is not much energy; The second part is the tricarboxylic acid cycle.

Citric acid cycle), this cycle is participated by a variety of enzymes, including a variety of intermediate products, to gradually decompose pyruvate, when the chemical bond is broken, and the chemical bond is broken to release energy. Because there are more broken bonds, more energy is released.
