Does the photolysis of water in the photoreaction phase in photosynthesis require the catalysis of e

Pigments are divided into 2 categories: chlorophyll a, which is not in a special state, and chlorophyll, which is not catalyzed.

When there is light on [other chlorophyll], [other chlorophyll] transmits light energy, and finally transmits to [a small amount of chlorophyll a in a special state], causing it to lose an electron and become a strong oxidant, oxidizing water ......

In addition, hydrolysis itself does not require enzymes, but if you want chloroplasts to continue hydrolysis, you still need enzymes to catalyze the synthesis of Nadph.

The lost electrons of chlorophyll a are accepted by NadP+ and become unstable Nadph under the action of enzymes, and Nadph decomposes in the dark reaction stage and releases NadP+ again. ”

No, only in dark reactions.

OK is not required.

Chlorophyll absorbs light energy.

Photosynthesis is divided into light reactions and dark reactions.

There are three steps in the photoreaction: photolysis of water (no enzymes are required).

ATP synthesis (requires ATP synthetase).

Nadph synthesis (requires oxidized coenzymes).

There are two steps in the dark reaction: CO2 immobilization (no enzyme required).

Reduction of C3 (enzyme required).

Total Reaction Formula: CO2 + H2O ---CH2O) + O2 where (CH2O) denotes sugars. Depending on whether light energy is required, it can be divided into two stages: light reaction and dark reaction.

Light Reaction Stage: Light is required to proceed Place: On the thylakoid film (Change of substance) Reaction Formula:

Light H2O---O2+2[H] ATP Formation of Water: ADP+PI+ Light Energy ---ATP (Energy Change) In the light reaction, light energy is converted into active chemical energy in ATP Dark reaction stage: can be carried out with and without light Place:

Chloroplast matrix (change of substance) reaction formula: Fixation of CO2: reduction of CO2 + C5---2C3 C3:

2c3+[h]+atp---ch2o）+c5+adp+pi

The photolysis of water does not require enzymes, it is due to the fact that chlorophyll a in a special state receives light energy from other pigments and loses electrons from water molecules.

This enzyme is a complex containing manganese ions called the oxygen-release complex. The fixation of CO2 requires an enzyme, which is a three-carbon compound catalyzed by C5 and CO2 under the catalysis of the enzyme. Hidden shirts.

Photolysis generally refers to photosynthesis.

Photolysis of water in the middle of the annihilation hall, that is, the water is decomposed by light to release oxygen from the collapsed bridge, which is a reaction that consumes energy. The photolysis of water takes place on a thin film of sac-like structures within chloroplasts, on which there are pigments that absorb and convert light energy, which is a physiological phenomenon unique to green plants.

Photolysis can break down a molecule into two small molecules or two free radicals.

Although it is possible to break down the molecule into two small ions, this is rare. Once photolysis produces free radicals, the properties of the free radicals produced are the same as those obtained by other means, except for the differences due to their being in the excited state.

Simulates cyanobacteria. The incomplete photosynthesis device will be designed to bionic photolyzed water, so that a large amount of hydrogen can be obtained.

During the photoreaction process, chlorophyll a in the state of Xunzhen is activated to seize the electrons of water, so that the water is directly decomposed into [H] and oxygen, without the action of the enzyme.

The photoreaction is for the synthesis of ATP and NADPH, so ATP synthase and NADPH synthase are required.

Not all biological reactions require the action of enzymes, and many reactions with electron transport do not, such as: photoreactions, water decomposition, electron transport in the respiratory chain.

1. The decomposition of water does not require enzymes, because in the process of light reaction, the leaf in the activated state lacks green a to seize the electrons of water, so that water is directly decomposed into [H] and oxygen, and the action of enzymes is not required.

2. In addition, the light reaction is to synthesize ATP and NADPH and provide energy for the dark reaction, so ATP and Nadph synthetase are required. 2H2O4[H]+O2 (do not enzyme) [H]+ADP ATP (ATP synthetase required) [H]+NADP NADPH (Nadph synthetase) where ATP and Nadph are involved in the dark reaction.

2. In addition, the light reaction is to synthesize ATP and Nadph and provide energy for the dark reaction, so ATP synthase and Nadph synthase are needed. 2H2O4[H]+O2 (do not enzyme) [H]+ADP Bi Deficiency ATP (ATP synthetase required) [H]+NADP Nadp (Nadph synthetase) in which ATP and Nadph are involved in the dark reaction.

No enzymes are required. The energy of photolyzed water is provided by light, and photolyzed water produces ATP to provide energy for the conversion of carbon dioxide into sugar. However, the hydrogen ions obtained by water photolysis move from the thylakoid to the matrix outward through the protein complex on the thylakoid membrane due to the difference in concentration, and the potential energy is used to synthesize ATP for dark reactions.

The energy of photolyzed water is provided by light, and photolyzed water produces ATP to provide energy for the conversion of carbon dioxide into sugar.

Photosynthesis is primarily the process of converting carbon dioxide and water into sugar and oxygen, specifically.

Photolysis of water produces the synthesis of hydrogen closed tung ions and oxy2H2O sedan 4[H]+2O2ATP, ADP+PI+energy ATP

Synthesis of sugar: CO2 + H2O (light energy, enzymes, chloroplasts) (CH2O) + O2 energy conversion process is to convert light energy into chemical energy ATP to provide energy for carbon dioxide to convert into sugar. It is carbon dioxide that produces sugar through an enzymatic reaction with ATP providing energy.

This is the basic energy conversion process, and it is easy to get the whole photosynthesis process apart and analyzed.

Photolysis of water does not require the involvement of enzymes.

Photolysis of water, which is carried out under the pigment in chloroplasts. A small number of special state pigments (central pigments) are excited to the excited state under light, lose electrons and become strong oxidants to seize electrons from water, 2H2O = (4H+) + O2 (H+: is hydrogen ion).

This is the photolysis of water. There is no enzyme involvement during this period.

Of course it does. Most biological reactions require the involvement of enzymes.

The decomposition of water does not require enzymes, because during the photoreaction, chlorophyll a in the activated state seizes the electrons of water, so that water is directly decomposed into [H] and oxygen, without the action of enzymes.

In addition, the light reaction is to synthesize ATP and NADPH and provide energy for the dark reaction, so ATP synthetase and Nadph synthetase are required. Approximate process:

2H2O4[H]+O2 (do not enzyme).

H] + ADP ATP (ATP synthetase required).

H]+NADP NADP (requires NADPH synthetase) where ATP and NADPH are involved in the dark reaction.
