What can mitochondria make and release by absorbing oxygen and organic matter?

Mitochondria are the main sites of cellular aerobic respiration. It is mainly divided into three stages: a. The first stage:

In the cytoplasmic matrix, one molecule of glucose is broken down 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. Reaction formula: C6H12O6 enzyme 2 pyruvate + 4 [H] + a small amount of energy B, the second stage:

Pyruvate enters the matrix of mitochondria, and the hydrogen in two molecules of pyruvate and 6 water molecules are all removed, and a total of 20 [h] are removed, and 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. Reaction formula: 2 pyruvate + 6H2O enzyme 20 [H] + 6CO2 + a small amount of energy 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 world 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. Reaction formula: 24[H]+6O2 enzyme 12H2O+ a lot of energy.

Absorbs oxygen, water and pyruvate, produces water and carbon dioxide, and releases a large amount of energy.

It is true that mitochondria are the main sites where aerobic respiration takes place.

Because aerobic respiration is divided into three phases, the first stage is carried out in the cytoplasmic matrix, where one molecule of glucose is broken down into two molecules of pyruvate, producing a small amount of [H] and releasing a small amount of energy. The second stage, which is carried out in the ** chondrial matrix, is the complete decomposition of pyruvate and water produced by the first stage into carbon dioxide and [H] and the release of a small amount of energy. The third stage is carried out on the inner membrane of the ** chondria, which is produced by the first two stages [H], after a series of chemical reactions, combined with oxygen to form water, and at the same time releases a large amount of energy.

From the perspective of these three stages, the last two stages are carried out in the ** chondria, and most of the energy comes from the reaction in the mitochondria, so the mitochondria are the main places for aerobic respiration.

The latter sentence, mitochondria is the main site of photosynthesis is wrong, the site of photosynthesis is chloroplast, and its site is chloroplast, not the main or not, because photosynthesis is carried out in chloroplasts.

Respiration Mitochondria are the site of oxidative metabolism in eukaryotes and are the sites where sugars, fats, and amino acids are eventually oxidized to release energy.

It is known that the air contains 21% oxygen, and oxygen can also react directly with many substances and is widely present in nature in the form of oxides. Oxygen is the key substance in metabolism, the basic property of the realization of the phenomenon of life, and is the first need for life activities. People inhale oxygen in the body through the lungs, and hemoglobin carries silver to the tissue cells in the body to participate in life activities.

Under physiological conditions, a small amount of active oxygen is generated in cells, which is of great significance in maintaining health such as antibacterial and anti-inflammatory. In addition, reactive oxygen species also play a regulatory role in redox-sensitive protein kinases in the signal transduction pathway. However, illness and physical and mental fatigue can induce excessive production of reactive oxygen species, resulting in an imbalance between antioxidant defenses and oxidative stress in the body.

Lipid peroxidation damage occurs by the over-produced reactive oxygen species acting on biofilms and macromolecular substances, and the over-produced reactive oxygen species are also closely related to the occurrence of various diseases. Reactive oxygen species in living organisms are mainly produced by mitochondria and some enzymatic reactions, but a few also come from non-enzymatic reaction processes such as reducing iron ions. Among them, the hydroxyl radical generated by hydrogen peroxide under the catalyst of metal ions is a reactive oxygen radical with strong reactivity and high harm.

If you look at **, you can know that carbon dioxide is produced in the second stage, and the location is the mitochondrial matrix.

Cellular respiration includes two types, aerobic and anaerobic respiration. Aerobic respiration refers to the process in which cells completely oxidize and decompose organic substances such as sugars through the catalytic action of enzymes with the participation of oxygen, producing carbon dioxide and water, and releasing a large amount of energy at the same time. Aerobic respiration is the main form of cellular respiration in higher animals and plants, so what is commonly referred to as cellular respiration refers to aerobic respiration.

The main site where cells undergo aerobic respiration is mitochondria.

The oxygen that is respired into the body by living organisms ends up as an electron acceptor in the respiratory chain in the mitochondria, which binds to hydrogen ions to form water.

Carbon dioxide produced by the respiration of living organisms** contains carbon organic matter in cells. When carbon-containing organic matter decomposes, carbon dioxide is produced through decarboxylation, which is eventually excreted from the body through respiration.

Take, for example, the decomposition of carbohydrate organic matter. Carbohydrate organic matter contains three elements: carbon, oxygen, and hydrogen. When decomposed in living organisms, carbon and oxygen form carbon dioxide. Hydrogen combines with oxygen that is breathed into the body to produce water.

The energy converters in the cell are mitochondria and chloroplasts, chloroplasts are the places where plants carry out photosynthesis, and through photosynthesis, the light energy is converted into chemical energy and stored in the organic matter manufactured; Mitochondria are the site of respiration, which can use some organic matter in the cell as fuel, so that these organic matter can be combined with oxygen, and after a complex process, it is converted into carbon dioxide and water, and at the same time the energy stored in the organic matter is released, and the energy released is used for cellular life activities Therefore, mitochondria are called the "power factory" of cellular energy Visible c is in line with the topic

Therefore, c

Mitochondria are the energy converters contained in both plant cells and animal cells Mitochondria are the sites where organisms carry out respiration, decompose organic matter, and release the chemical energy stored in organic matter for cell utilization

The leaf cells of the plant body contain chloroplasts, chlorophyll in chloroplasts.

Able to absorb light energy, chloroplasts convert light energy into chemical energy, which is stored in the organic matter it produces. Both plant and animal cells contain mitochondria.

If the cell is compared to the noise of a car, the mitochondria are similar to the engine, the engine fuels the car to power the car, and the mitochondria use some organic matter in the cell as fuel, so that these organic matter combines with oxygen, and through a complex process, it is converted into carbon dioxide.

and water, while releasing chemical energy from organic matter.

Thus, chloroplasts and mitochondria are energy converters in cells.

It is converted into carbon dioxide and water, and energy is released.

a. The third stage of aerobic respiration occurs in the inner mitochondrial membrane, which contains enzymes related to Xunzi, so the types of proteins on it are not the same, and a is wrong;

b. The process of decomposition of glucose into pyruvate occurs in the cytoplasmic matrix slip guess, b is wrong;

c. The third stage of aerobic respiration occurs in the inner mitochondrial membrane, and the release of energy per mu is the maximum, and c is correct;

d. Mitochondria contain DNA and RNA, and D is wrong
