Pick 1(glucose + cells after homogenization).
2.(pyruvate + cells after homogenization).
3.(pyruvate + mitochondria).
All three of these are possible.
Respiration does not necessarily depend on the complete cellular structure or organelle structure. As long as you have the enzymes and associated proteins necessary for respiration, you will be fine. This is because biochemical reactions are only related to substrates and catalysts (enzymes).
As long as both the substrate and the enzyme are present, the reaction can take place.
Not to mention what kind of cell homogenate, even if the enzymes involved in the reaction and the proteins related to electron transport are directly extracted and placed in a test tube, and the substrate is added, the reaction can still occur and carbon dioxide is produced.

Add in a test tube.
1.(glucose + cells after homogenization).
2.(pyruvate + cells after homogenization).
3.(pyruvate + mitochondria).
Higher animal and plant cells have aerobic respiration, which breaks down glucose and produces carbon dioxide in three stages. In the first stage, glucose is broken down to produce pyruvate and [H], which release a large amount of energy; After pyruvate enters the mitochondria, it completes the second stage, generates carbon dioxide and [H], releases a large amount of energy, and is carried out in the ** chondrial matrix; In the third stage, the [h] produced in the first two stages is combined with oxygen to produce water, releasing a large amount of energy.
It can be seen that to produce carbon dioxide, it is necessary to have pyruvate and mitochondria, or related enzymes.
1.(glucose + cells after homogenization) [The cell fluid after homogenization contains the enzymes required for the first and second stages].
2.(pyruvate + cells after homogenization) [there are enzymes associated with the second phase]3(pyruvate + mitochondria) [Mitochondrial structure intact] are all eligible to produce carbon dioxide.

The whole process of aerobic respiration can be divided into three stages: the first stage (called glycolysis), one molecule of glucose is broken down into two molecules of pyruvate, and a small amount of hydrogen (denoted by [h]) is produced in the process of decomposition, and a small amount of energy is released at the same time. This stage is carried out in the cytoplasmic matrix; In the second stage (known as the tricarboxylic acid cycle or citric acid cycle), pyruvate undergoes a series of reactions to break down into carbon dioxide and hydrogen, while releasing a small amount of energy.
This stage is carried out in the ** chondria ; In the third stage (respiration electron transport chain), hydrogen produced in the first two stages undergoes a series of reactions that combine with oxygen to form water, while releasing a large amount of energy. This stage is also carried out in the ** granula. Each of the above three chemical reactions is catalyzed by different enzymes.
In the organism, 1mol of glucose is completely oxidized and decomposed, and a total of 2870kJ of energy is released, of which about 977kJ of energy is stored in ATP (32 ATP), and the rest of the energy is lost in the form of heat energy.
-
The third and the first. The decomposition of glucose is divided into three parts, first in the cytoplasm it is decomposed into pyruvate and a small amount of [H] (a macromolecular organic matter, not hydrogen), then the pyruvate and water in the ** strome matrix are completely decomposed into [H] and a small amount of energy, and finally** the inner membrane of the chondrea reacts with oxygen to produce water and carbon dioxide, as well as a large amount of energy.
-
Glucose is changed to pyruvate in the cytoplasmic matrix, a process that does not produce carbon dioxide. After pyruvate enters the mitochondria, it oxidizes to produce carbon dioxide. Homogenization is disrupting the cytoplasmic matrix.
-
3.Yes, yes, pyruvate first reacts with water in the mitochondrial matrix to obtain carbon dioxide and reducing hydrogen.
After homogenizing the cells organelles get destroyed without intact mitochondria.
Hence 1It can only be the conversion of glucose to pyruvate in the cytoplasmic matrix without the production of carbon dioxide;
2.The same is not true.
I feel this way and I hope it helps you

The total process of organic matter in an organism undergoes a series of oxidative decomposition in the cell to finally produce carbon dioxide or other products and release energy, which is called respiration.
The process of decomposing one's own organic matter into inorganic matter and returning it to the inorganic environment and releasing energy is called alienation. The essence of dissimilation is the oxidation of macromolecules, including proteins, lipids, and sugars, in living organisms and the release of energy during the oxidation process. The energy is absorbed by the reaction of ADP to ATP, and ATP is used as an energy storage substance for other needs.
To put it simply, assimilation is to turn the non-self into oneself; Alienation is the opposite, turning oneself into something that is not oneself. Assimilation is an important process in metabolism, which is the process of recombining digested nutrients to form organic matter and store energy.
The metabolism of yeasts, like many microorganisms, involves the increase or accumulation of energy (dissimilation) and the consumption of energy or biosynthetic pathways (assimilation), which include the transfer of simple atoms, clusters of atoms, or electrons. Growth is the balance of these redox reactions, and part of the energy released by dissimilation can be used to promote the synthesis of proteins and other substances needed by cells. Yeast is widely used in production, and in addition to the well-known sake brewing and dough making, it can also be used to produce organic acids and extract a variety of enzymes.

Write the equation between anaerobic and aerobic respiration, the ratio of glucose to CO2 in anaerobic inhalation is one to two, and in aerobic respiration it is one to six, because the CO2 produced is equal, so the ratio is 2:6=1:3
-
When there is no oxygen: C6H12O6 = 2C2H5OH+2CO2
When aerobic: C6H12O6 + 6H2O + 6O2 = 6CO2 + 12H2O + energy.
According to this formula, it can be seen.

What is the use of lactic acid produced by plant respiration and what is it used for animals?
A: The gas produced by cellular aerobic respiration is carbon dioxide, which is the case in animals and plants. Whereas, there are two types of anaerobic respiration:
Alcoholic type, lactic acid type. The alcohol type produces carbon dioxide and alcohol, and the lactic acid type produces only lactic acid. Animal cells undergo lactic acid anaerobic respiration only.
Therefore, the way through which plant cells produce carbon dioxide is aerobic respiration and alcohol-type anaerobic respiration. Animal cells are aerobic respiration.
Respiration is divided into aerobic respiration and anaerobic respiration:
Aerobic respiration reaction: Phase 1 C6H12O6 enzyme (Place: cytoplasmic matrix) = 2 pyruvate + 4 [H] + energy (2ATP).
Phase 2 pyruvate + 6H2O enzyme (site: mitochondrial matrix) = 6CO2 + 20 [H] + energy (2ATP).
Stage 3 24[H]+6O2 enzyme (Location: Inner Mitochondrial Membrane) = 12H2O+ Energy (34ATP).
The total reaction formula C6H12O6 + 6H2O + 6O2 enzyme 6CO2 + 12H2O + bulk energy (38ATP).
Why does lactic acid produced by anaerobic respiration in animals make muscles sore?
Answer: Glucose produces lactic acid by anaerobic respiration, which is highly acidic, can the muscle be acidic? pH value.
Difference Between Lactic Acid and Lactic Acid Bacteria:
A: Lactic acid bacteria are biological bacteria that promote the production of lactic acid, which is a chemical substance.
Lactic acid is an organic substance, hydroxypropionic acid, pure lactic acid is a colorless liquid, and industrial products are colorless to light yellow liquid. Odorless and hygroscopic. Relative density.
Melting point 18. Boiling point 122 (2kpa). Refractive index nd(20).
It is miscible with water, ethanol and glycerol, and insoluble in chloroform, carbon disulfide and petroleum ether. When it is heated and decomposed under atmospheric pressure and concentrated to 50%, part of it becomes lactic anhydride, so the product often contains 10%-15% lactic anhydride.
Lactic acid bacteria are microorganisms that are anaerobic.

aRespiration rate should be determined by measuring the rate of oxygen consumption. So x should be sodium hydroxide, which absorbs the carbon dioxide exhaled by the larvae, and because oxygen is consumed, the total volume of the gas decreases and the droplets shift to the left.
The volume of droplet movement in b20-30min is 130-65=65mm3, then the average oxygen absorption rate should be.
C larvae do not survive in pure N2 conditions.
dThe so-called controlled experiment should be to experiment with changes in the independent variables. Liquid x is an irrelevant variable in this experiment and should be controlled equally. The control could replace the Drosophila larvae with the dead Drosophila larvae, all else being equal.

Aerobic respiration: 1 glucose 6O2 6CO2
Anaerobic respiration: 1 glucose 2CO2
The ratio of the amount of CO2 released to the absorption of O2 is 4 3 [(6+2) 6], so half of the glucose (mol) is used for aerobic respiration and the other half is used for anaerobic respiration. Aerobic respiration consumes moles of glucose, and the number of moles of O2 that needs to be absorbed is.
Dizzy, buy a reference book.
First, the dominant recessive nature of albinism and sickle anemia was determined, and according to the left half of Figure 1, it can be concluded that anemia is a recessive genetic disease, which is bb; Then look at Figure 2, because if it is normal, it can be cut, and if it is not normal, it can't, so B is normal, C is albino, and both are homozygous, only A is heterozygous (because A can cut out three pieces: DNA is a double helix structure, only one of A can be cut, B can be cut all of them, cut into two short and two long, C is not cut) Because albinism is a recessive genetic disease, it is AA, so it can be known that B is AA and C is AA >>>More
