Respiration absorbs oxygen and releases carbon dioxide, and photosynthesis absorbs carbon dioxide and releases oxygen.
The carbon cycle in the biosphere is mainly manifested in the absorption of carbon dioxide from the atmosphere by green plants, which are converted into glucose and released by photosynthesis with the participation of water, and the organism uses glucose to synthesize other organic compounds.
Organic compounds are transported through the food chain and become part of other organisms such as animals and bacteria. A part of the carbohydrates in living organisms are oxidized to carbon dioxide and water through respiration as an energy source for the metabolism of organisms, and the energy stored in them is released.
The circulating state of oxygen in nature. Oxygen is consumed to produce carbon dioxide for respiration in plants and animals, as well as for combustion in human activities. However, the photosynthesis of plants absorbs a large amount of carbon dioxide and releases oxygen, thus forming the oxygen cycle of the biosphere.
Importance: Plants and photosynthetizing microorganisms absorb carbon from the atmosphere at a rate roughly equal to the rate at which carbon is released into the atmosphere through biological respiration, so the amount of carbon dioxide in the atmosphere is fairly stable until it is disturbed by human activities.
Taking into account natural fires, carbon sequestration by plants and the like is more than carbon gasification caused by animals, etc. Petrocoal is a by-product of excess carbon sequestration.

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. Anaerobic respiration generally refers to the process in which plant cells decompose organic matter such as glucose into incomplete oxidation products through the catalysis of enzymes under anaerobic conditions, and at the same time release a small amount of energy.
Photosynthesis, or photosynthesis, is a biochemical process in which plants, algae, and certain bacteria use photosynthetic pigments to convert carbon dioxide (or hydrogen sulfide) and water into organic matter and release oxygen (or hydrogen) under the irradiation of visible light.
The link between photosynthesis and aerobic respiration:
Aerobic respiration provides the main energy for the physiological activities of the cell, which provides energy for the transport of substances for photosynthesis.
From the perspective of the carbon cycle, the carbon dioxide released by aerobic respiration happens to be the raw material for chloroplast photosynthesis, while the oxygen required by mitochondria is provided by photosynthesis.
Both require the right temperature and both need to be catalyzed by enzymes, although the optimal temperature is different.
Difference Between Photosynthesis and Aerobic Respiration:
From the perspective of material substitution, aerobic respiration is catabolism, while chloroplast's aerobic respiration is anabolism.
Aerobic respiration does not require light, whereas photosynthesis of chloroplasts requires light.
From the perspective of the carbon cycle, aerobic respiration releases carbon dioxide, while photosynthesis fixes carbon dioxide.

Photosynthesis is the synthesis of water and oxygen (CH2O)N by plants, i.e. starch, glucose, etc.
Aerobic respiration breaks down organic matter, such as glucose, in the mitochondrial and cytoplasmic matrix of the cell.
Animals and plants can have this aerobic respiration (e.g. jogging, and normal, non-strenuous exercise).
The process of combining the light plexes:1Photoreaction stage The chemical reaction in the first stage of photosynthesis must have light energy to proceed, and this stage is called the photoreaction stage.
The chemical reaction in the photoreaction stage is carried out on the thylakoids within the chloroplast. Dark Reaction Phase The chemical reaction in the second phase of photosynthesis can be carried out without light energy, and this stage is called the dark reaction phase. The chemical reactions in the dark reaction phase are carried out in the matrix within the chloroplast.
The photoreaction stage and the dark reaction stage are a whole, and in the process of photosynthesis, the two are closely related and indispensable.
A common phenomenon of aerobic respiration and anaerobic respiration.
1 From the perspective of the changes in matter and energy, both are the decomposition of organic matter to release energy.
2 From the perspective of the reaction process, the first step of the reaction of these two types of respiration is to break down glucose into pyruvate in the cytoplasmic matrix.
3 From the perspective of biological evolution, the atmosphere of the primordial Earth did not contain oxygen. Therefore, the respiration mode of organisms at that time was anaerobic respiration. When autotrophic organisms such as cyanobacteria appeared, there was oxygen in the atmosphere, and aerobic respiration occurred.
It can be seen that aerobic respiration is developed on the basis of anaerobic respiration.

1. The types of organisms that occur are different. Aerobic respiration generally refers to animals and can also refer to plant microorganisms, but photosynthesis can only occur in green plants.
2. The transformation of energy has different meanings. Photosynthesis is to create and store energy for the organism itself, while aerobic respiration is to consume the energy of the organism itself.
3. The cell organization of the organism that occurs is different. Photosynthesis generally occurs in the chloroplasts of plant cells, and aerobic respiration generally occurs in the mitochondria of living organisms.
Connection: Carbon dioxide produced by aerobic respiration sometimes enters chloroplasts as a raw material for photosynthesis.

Summary. Aerobic respiration is a process in which an organism uses oxygen for energy metabolism, in which water is an essential substance. During aerobic respiration, the organism combines oxygen with organic matter, releases a large amount of energy, and produces a large number of water molecules.
Photosynthesis is also a process in which organisms use solar energy for energy metabolism, in which water molecules are also involved. In the process of photosynthesis, plants convert solar energy into chemical energy and store it in organic matter, and in this process, a large number of water molecules are also produced. In conclusion, water can participate in both aerobic respiration and photosynthesis, both of which are necessary processes for energy metabolism in living organisms using external energy.
Aerobic respiration is a process in which an organism uses oxygen for energy metabolism, in which water is an essential substance. During aerobic respiration, the organism combines oxygen with organic matter to swim up, releasing a large amount of energy and producing a large number of water molecules. Photosynthesis is also a process in which organisms use solar energy for energy metabolism, which also requires water molecules.
In the process of photosynthesis, plants convert solar energy into chemical energy and store it in organic matter, and in this process, a large number of water molecules are also produced. In conclusion, water can participate in both aerobic respiration and photosynthesis, both of which are necessary processes for the organism to use external energy for energy metabolism.
Therefore, we can see that water can participate in both aerobic respiration and photosynthesis. It plays an important role in both metabolic processes, allowing both metabolic processes to proceed normally.
Do both prokaryotic and eukaryotic cells have phospholipids in their cell membranes?
Yes, both prokaryotic and eukaryotic cells contain phospholipids in their cell membranes.
The addition of phosphoric acid and copper sulphate solutions can also effectively degrade cyanide, as these substances can be decomposed into harmless substances such as water, carbon oxide and sulfate through electron transfer.
Are the metabolic activities of mitochondria and chloroplasts related to energy.
Yes, both mitochondria and chloroplasts have a relationship with energy. Mitochondria use redox reactions to produce ATP early, while chloroplasts use photobonding finch synthesis to produce ATP.
The biofilm composition of the Golgi apparatus and endoplasmic reticulum is similar, are their biofilms directly attached.
The biofilm composition of the Golgi apparatus and the endoplasmic reticulum is similar, but they are not directly connected. There is an intermediate layer between them, called cell membrane proteins, that forms a modified and intact cell wall.
When a large amount of potassium ions and other substances accumulate in a cell, it mainly relies on active transport to enter the cell?
Yes, when a large amount of potassium ions and other substances accumulate in the cell, it mainly relies on active transport to enter the fine dismantling cell. Active transport of Chanai jujube refers to the use of energy in the cytosol to help substances pass through the cell membrane, so that substances can enter or leave the cell.
Shouldn't the value of vegetables be pesticide-free and organic?
From the perspective of endosymbiotic, the chloroplasts in modern higher plants or lower eukaryotic photosynthetic algae actually come from cyanobacteria. In other words, in the long evolutionary process, the ancestors of plant cells swallowed cyanobacteria and found that they could photosynthesize to provide energy, so they kept them in their bodies. After a long time, cyanobacteria gradually lose other functions that have nothing to do with photosynthesis, and the whole becomes a part of the plant cell. >>>More
In mesophyll cells, the oxygen produced by photosynthesis should first meet its own needs, that is, mitochondria consume oxygen to produce water. When the light is strong, photosynthesis produces more oxygen than cellular respiration consumes, so the excess is released through the stomata. When there is little or no light, plant cells need to absorb oxygen from their surroundings for respiration.
