What is the chemical reaction formula of aerobic respiration?

C6H12O6+6O2 6CO2+6H2O Answer Supplement The three phases of aerobic respiration.

a. The first stage: in the cytoplasmic matrix, one molecule of glucose is decomposed into two molecules of pyruvate, and 4 [H] enzymes are removed at the same time; During the breakdown of glucose, a small amount of energy is released, and part of the energy is used to synthesize ATP, producing a small amount of ATP. Reactive:

C6H12O6 enzyme 2 pyruvate +4 [H].

b. The second stage: pyruvate enters the matrix of mitochondria, and the hydrogen in the two molecules of pyruvate and 6 water molecules are all removed, and a total of 20 [h] are removed, and the acetone is oxidized and decomposed into carbon dioxide; A small amount of energy is released in this process, part of which is used to synthesize ATP, producing a small amount of energy. Reactive:

2 pyruvate + 6H2O enzyme 20[H]+6CO2

c. The third stage: on the inner membrane of the chondria, a total of 24 [H] shedding in the first two stages are combined with 6 O2 produced by absorption from the outside or chloroplast photosynthesis to form water; In this process, a large amount of energy is released, and part of this energy is used to synthesize ATP, producing a large amount of energy. Reactive:

24[H]+6O2 enzyme 12H2O

The first stage of C6H12O6 enzyme cytoplasmic matrix = 2 pyruvate (C3H4O3) + 4 [H] + energy (2ATP).

Phase 2 Pyruvate (C3H4O3) + 6H2O enzyme Mitochondrial matrix = 6CO2 + 20 [H] + energy (2ATP).

The third stage 24[H]+6O2 enzyme inner mitochondrial membrane = 12H2O+ energy (34ATP).

The total reaction formula C6H12O6 + 6H2O + 6O2 enzyme 6CO2 + 12H2O + bulk energy (38ATP).

1. In the cytoplasmic matrix.

The first stage of aerobic respiration occurs, i.e

C6H12O6 2C3H4O3 (pyruvate.

Lactic acid. Fermentation: C6H12O6 --enzyme - 2C3H6O3 (lactic acid) + a small amount of energy.

Alcoholic fermentation: C6H12O6 -- enzyme - 2C2H5OH (alcohol) + 2CO2 + a small amount of energy.

Anaerobic respiration process:

Phase 1:

in the cytoplasm. The stroma is exactly the same as the first stage of aerobic respiration. i.e. one molecule of glucose.

Pyruvate is broken down into two molecules under the action of enzymes.

During the process, a small amount of [H] and a small amount of energy are released.

Reaction formula: C6H12O6 + enzyme 2C3H4O3+4[H]+2ATP (small amount).

Phase 2:

In the matrix of the cytoplasm, pyruvate is catalyzed by different enzymes and decomposes into alcohol and carbon dioxide.

or converted to 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.

But in the university and biological research stage, the second stage of anaerobic respiration of the cell actually produces a little bit of energy. The reason why the new textbook ignores it is simply that it is produced too little to synthesize ATP, and it is emitted in the form of heat. Therefore, in high school, it can be considered that the second stage of anaerobic respiration of cells has the release of energy, but does not synthesize ATP.

Reaction formula: 2C3H4O3+4[H]+ enzyme 2C3H6O3 (lactate) + energy (small amount) or.

2C3H4O3+4[H]+ enzyme 2C2H5OH (alcohol) + 2CO2+ energy (small amount).

Lactic acid fermentation C6H12O6 --enzyme - 2C3H6O3 (lactic acid) + a small amount of energy; Alcoholic fermentation: C6H12O6 -- enzyme - 2C2H5OH (alcohol) + 2CO2 + a small amount of energy.

Anaerobic respiration refers to a special type of respiration with low productivity efficiency that occurs when anaerobic or facultative anaerobic microorganisms use exogenous inorganic oxides or organic substances as terminal hydrogen (electron) acceptors under anaerobic conditions.

Phase 1:

1 glucose + 2ADP + 2PI + 2 [NAD] 2 pyruvate + 2 [NADH + H+] + 2ATP

Phase 2:

2 pyruvate + 2 [nad] + 2 coenzyme A 2 acetyl Coa + 2 [nadh + H+] + 2CO

2 acetyl CoA + 6H O + 6 [Nad] + 2 [Fad] + 2ADP + 2Pi 2 Coenzyme A + 6 [Nadh + H+] + 2 Fadh2 + 2ATP + 4CO

Stage 3 :

28adp+28pi+10[nadh+h+]+2fadh2+6o₂→ 28atp+12h₂o+10[nad]+2[fad]

The whole process of anaerobic respiration can be divided into two stages, the first stage C6H12O6 enzyme (site: cytoplasmic matrix) = 2 pyruvate + 4 [H] + energy (2ATP); Phase 2 pyruvate (site: cytoplasmic matrix) = 2C2H5OH + 2CO2 + small amount of energy or 2C3H6O3 (lactate) + energy; Total Reaction Formula:
