How ADP is converted into ATP and how energy works can be exemplified by the conversion mechanism in

Photosynthesis can be divided into 3 major steps.

1. Primary reaction, including light absorption, transmission and conversion.

2. Electron transport and photosynthetic phosphorylation to form active chemical energy (ATP and Nadph).

3. Carbon assimilation, which converts active chemical energy into stable chemical energy.

The primary reaction refers to the process of photosynthesis from the time the chlorophyll molecule is excited by light to the first photochemical reaction, including the absorption, transfer and conversion of light energy by the pigment molecule. This involves the concept of a photosynthetic unit, please encyclopedia.

Photochemical reactions.

Among them, there are more concentrating pigments, and the main function of concentrating pigments is to collect light energy and transfer energy to the reaction center pigment molecules. The reaction center is a membrane protein complex that converts light energy into chemical energy, which contains special chlorophyll a pairs involved in energy conversion, electron acceptor molecules such as demagnesium chlorophyll (chlorophyll where magnesium is replaced by hydrogen) and quinone. The special chlorophyll a pair receives energy, transforms into an excited state, and surrenders an electron to the demagnesium chlorophyll, which is transmitted to the electron acceptor of the non-pigmented molecule located in the outer membrane of the thylakoid (e.g., quinone, coenzyme Q) due to electron transport to produce an irreversible charge separation.

Finally, the electrons are passed into the electronic respiratory chain, and the electronic respiratory chain can be encyclopediaded by itself.

Electron transport and photosynthetic phosphorylation.

The transfer of electrons through a series of electron transporters causes the cleavage of water to release oxygen and the reduction of NaDP+ to Nadph, and the formation of ATP through photosynthetic phosphorylation

There is also the structural mechanism of ATP synthase, which belongs to the first-level discipline of biochemistry, and there are too many things involved... I can't say enough...

Mutual conversion of ATP and ADP:

Under the action of ATP hydrolase, the high-energy phosphate bond away from A in ATP is hydrolyzed, and the energy in it is released, and ADP and PI are generated at the same time.

Under the action of ATP synthase, ADP accepts energy and conjugs to a PI to convert it into ATP.

The reaction of ATP and ADP is irreversible, and the matter is reversible and the energy is irreversible.

ADP and PI can be recycled, so the substance is reversible; However, the energy required to form ATP is by no means the energy released by the hydrolysis of ATP, so the energy is irreversible.

ATP is a high-energy phosphoric acid compound, in the cell, it can be converted with ADP to achieve energy storage and release, so as to ensure the energy of various life activities of the cell**.

There are two main ways to produce ATP: one is that chloroplast-containing cells in plants produce ATP during the light reaction stage of photosynthesis; The other is that all living cells are able to produce ATP through cellular respiration.

When ATP undergoes hydrolysis, ADP is formed and a phosphate group is released, along with the release of energy. This energy is used in the cells, the movement produced by muscle contraction, the activity of nerve cells, and everything else in the organism uses the energy produced by the hydrolysis of ATP.

Due to the presence of the N element on the imidazole ring and the benzene ring, as well as the N element on the amino group on the benzene ring, they both have lone pairs, and when metal ions are added to the solution, a coordination reaction may occur.

The above content refers to Encyclopedia - Adenosine Diphosphate

Answer: In green plants, the physiological processes of ADP conversion to ATP are (photosynthesis) and (respiration as auspicious oak).Analysis:

In the process of photosynthesis, in the light reaction, the adp is converted into ATP, that is, the photosynthesis is converted into active chemical energy. Respiration decomposes organic matter and converts ADP into Zhengma ATP, which provides energy for the life activities of organisms.

Reciprocal Zen type surplus transformation:

ATP - Enzyme (Hydrolase) - ADP + PI + Energy ADP + PI + Energy - Another Enzyme (Synthase) - Rent Chain - ATP Meaning: ATP is the direct energy of the living body**, and the energy released by the decomposition of the Hosohe Roll cell is provided to every action made by the human body.

ADP is mainly used to receive and store energy as ATP

01 First of all, we need to understand the structure of ATP, the full name of ATP is adenine nucleoside triphosphate, also referred to as adenosine triphosphate, which is composed of one molecule of adenine, one molecule of ribose and three molecules of phosphate groups.

02 Then, let's look at the structure of ADP, the full name of ADP is adenine nucleoside diphosphate, also referred to as adenosine diphosphate, which is composed of one molecule of adenine, one molecule of ribose and two molecules of phosphate groups.

03 In summary, it can be seen that there is a phosphoric acid and a high-energy phosphoric phosphate bond between ATP and ADP.

04 Therefore, in living organisms, ATP is usually hydrolyzed under the action of ATP hydrolase to lose a phosphate group, that is, to break a high-energy phosphate bond, produce pure energy, and release the product. The formula is: ATP (enzyme involvement) = ADP + PI + energy.

05 At the same time, the residual foot ADP in the organism can also synthesize ATP under the action of ATP synthetase. The formula is: ADP + PI + Energy = ATP (enzyme participation).

06 However, the conversion of the two is not a reversible reaction, and it should be noted that there are three reasons.

07 The first point is from the reaction conditions. In the decomposition of ATP, it is ATP hydrolase that catalyzes the reaction; In ATP synthesis, it is ATP synthetase that catalyzes the reaction. We all know that the reaction of enzymes is specific and the reaction conditions are different.

08 The second point, from the perspective of energy, the chemical energy of ATP hydrolysis energy** in ATP, which is far away from adenosine, is mainly used for various physiological activities in our organisms, such as running, talking, etc.; In ATP synthesis, the energy ** is the chemical energy released from the decomposition of organic matter through respiration and the energy in phosphocreatine, which shows that the ** and destination of energy are different, so the reaction is irreversible.

09 The third point is that the synthesis sites of ATP are cytoplasmic matrix and mitochondria, while ATP has many decomposition sites, and almost all cells in the body can decompose ATP. The place is different, and the reaction is irreversible.

10 Through the above analysis, I believe you have known the process of ATP and ADP mutual transformation, remember to praise me for my diligence.
