What is the relationship between nitrogen assimilation and respiration and photosynthesis?

The absorption, assimilation and utilization of nitrogen play an extremely important role in the metabolism of plants, which is related to the growth, development, yield and quality of plants. The assimilation process of nitrogen is one of the most basic assimilation processes in the plant body. The nitrogen sources used by plants can generally be divided into two types: nitrate nitrogen and ammonia nitrogen.

All these indicate that the relationship between carbon metabolism and nitrogen assimilation in leaves is close and complex. Light-driven nitrogen assimilation in plants is actually associated with photosynthesis.

Just as ancient, the mechanisms that regulate the complex interactions between carbon and nitrogen metabolism have undergone a long evolutionary process. Compared to any other major physiological process, nitrogen assimilation can better unify photosynthesis and respiratory metabolism into an interdependent system. And in.

C3 in plants because of photorespiration.

The system has become more complex. Numerous interactions between carbon and nitrogen metabolism have been studied at all levels and in plant anatomy. Intracellularly, extensive collaboration of carbon and nitrogen metabolism occurs in areas such as chloroplasts.

Mitochondria, peroxisomes, and cytoplasm.

and so on. The change of the relative state of carbon and nitrogen will cause physiological and morphological changes in the organs, and eventually lead to changes in the whole plant. Many of the key interactions between carbon and nitrogen metabolism occur between chloroplasts and mitochondria; This allows for the proper energy balance and assimilate distribution, while avoiding excessive disruption of the oxygen reduction balance within the cell.

Photosynthesis and respiration.

The rate of 's fluctuates in a circadian cycle in almost every plant studied, and a variety of external inducing and environmental factors are necessary to precisely and appropriately adjust their relative rates; This prevents the plant from frequently switching between energy- or resource-based metabolisms. All of this requires the integration of regulating the expression and activity levels of various enzymes involved in photosynthesis and respiration to coordinate the distribution of carbon and the assimilation of nitrogen.

High 3 Biology] Photosynthesis and Respiration.

Respiration. It is divided into aerobic respiration and anaerobic respiration.

Aerobic Respiration Reaction: Phase 1 C6H12O6 enzyme (Location: Cytoplasmic matrix.

2 pyruvate. 4[H]+ energy (2ATP).

Stage 2 Pyruvate + 6H2O enzyme lead suspicion (Location: 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).

Photosynthesis. Total Reaction Formula: CO2+H2O(Light) (CH2O)+O2 Condition: Light.

It is divided into a light reaction stage and a dark reaction stage.

1.The photoreaction phase is in chloroplasts.

The membrane of thylakoids:

Including photolysis of water i.e. H2OO2 + H].

and ADP ATP

2.The dark reaction phase is in the cytoplasmic matrix:

A fixed invocation that includes CO2 i.e. CO2 2 C3

The recombination of the products of the photoreaction [H] and ATP converts C3 to organic matter (i.e., carbon.

aqueous compounds) as well as C5

The reaction formula of photosynthesis and respiration is as follows:

The chemical equation for photosynthesis in plants: co + h o = ch o + o.

Chemical equation for respiration: C H O + 6O = 6Co + 6H O + Energy (Catalyst: Enzyme).

Green plants use the energy provided by light to synthesize organic matter such as starch from carbon dioxide and water in chloroplasts, and convert light energy into chemical energy and store it in organic matter, a process called photosynthesis.

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.

Introduction to Chemical Equations:

Chemical equation, also known as chemical reaction equation, is a formula that uses chemical formulas (organic substances in organic chemistry generally use simple structural formulas) to express the chemical reactions of substances.

The chemical equation not only indicates the reactants, products, and reaction conditions. At the same time, the stoichiometric number represents the quantitative relationship between the reactants and the product substances, and the mass relationship between the substances can also be expressed through the relative molecular mass or relative atomic mass, that is, the mass ratio between the substances. For gas reactants and products, the volume ratio can also be obtained directly from the stoichiometric number.

Photosynthesis and respiration are two basic metabolic processes in living organisms. Photosynthesis refers to the process by which plants convert carbon dioxide and water into organic substances through light energy, while releasing oxygen. Respiration refers to the process by which organisms react organic matter with oxygen to produce energy and carbon dioxide water.

There is an interdependent relationship between photosynthesis and respiration. Plants synthesize organic matter through photosynthesis, which provides energy and nutrients to plants, as well as food for other living beings. Respiration, on the other hand, is the process of breaking down these organic substances into energy and garbs for plants.

Therefore, photosynthesis and respiration are two interrelated processes, and the balance between the two is essential for the growth and development of plants. If the photosynthesis process is disturbed, such as water shortage, high temperature, etc., the plant's ability to synthesize organic matter will be reduced, resulting in stunted plant growth. Similarly, if the respiration process is disturbed, such as insufficient oxygen**, the plant will not be able to decompose organic matter into energy, affecting the growth and development of the plant.

Photosynthesis is the basis of respiration. In the process of photosynthesis, plants or algae absorb light energy through the pyrellin and convert it into organic matter. Oxygen needs to be consumed in this process, so respiration is developed on the basis of photosynthesis.

2.Photosynthesis and respiration promote each other. The oxygen produced by the photosynthesis bench can assist in oxidative metabolism during respiration, promote the decomposition of organic matter and release energy. The carbon dioxide produced by respiration can also promote the light and reaction in photosynthesis.

3.The balance between photosynthesis and respiration is also an important regulatory mechanism for life activities. In nature, the balance between photosynthesis and respiration is always maintained to ensure that living organisms can continue to produce energy and maintain normal life activities.

The green leaves of higher plants integrate photosynthetic carbon assimilation and nitrogen assimilation. The photochemical process of photosynthesis in green leaves not only assimilates COZ into carbohydrates, but also participates in the process of nitrite reduction into ammonia and ammonia into amino acids in chloroplasts. Therefore, there is a close relationship between photosynthesis light reaction, carbon assimilation and nitrogen assimilation, and studying the interconnection between these processes will help us regulate the balance of carbon and nitrogen metabolism in plants.

This article attempts to summarize the research in this area. 1. The relationship between photosynthesis and nitric acid assimilation.

The nitrogen absorbed by most plants from the soil is mainly nitrate nitrogen'52].It is estimated that plants on the Earth's surface absorb about 20 billion tons of nitrate nitrogen from the soil every year. The nitrate nitrogen entering the plant must be reduced to ammonia before it can be further converted into organic nitrogen-containing compounds.

Both the roots and leaves of plants are sites of nitric acid assimilation, with some roots being primary and others being primary, depending on the species of plant. In general, nitric acid assimilation in green groups is much more active than in non-green tissues, and at least 10 electrons are required for the reduction of nitrates from highly oxidized nitrates to highly reduced amino groups [32].Therefore, nitric acid assimilation needs to be linked to the process of producing reducing agents. Studies done with microorganisms and higher plants have shown that nitric acid assimilation is closely related to respiration and photosynthesis.

The assimilation of nitric acid in the roots of higher plants is strongly dependent on respiration, which is due to respiration.

This ** is very complete, go to Qingdongqin to see.

Respiration is divided into aerobic respiration and anaerobic respiration, and the reactants are mainly glucose

Changes in the substance of aerobic respiration Glucose produces pyruvate and H in the first stage, pyruvate and water produce carbon dioxide and H in the second phase, H and oxygen used produce water in the third phase, and energy is released in all three phases.

Anaerobic respiration changes in glucose, lactic acid, or alcohol and carbon dioxide.

Photosynthesis consists of two phases: light reaction and dark reaction

Photoreactive substances change the synthesis of water into H and oxygen, ATP.

The changes of dark reactive substances are as follows: carbon oxide is fixed by C5 to form C3, and C3 is reduced by H to form organic matter such as C5 and glucose.

Relationship between photosynthesis and respiration: Respiration and photosynthesis are interdependent.

Respiration and photosynthesis are the reasons for the interdependence of the relationship:

1. The organic matter decomposed by plant respiration is the product of photosynthesis. Without organic matter made by photosynthesis, respiration cannot take place;

2. When plants are photosynthesizing, the energy required for the absorption of raw materials and the transportation of products is released by respiration. There is no respiration or energy supply, and photosynthesis is carried out without the milling method.
