There is a distinction and connection between photosynthesis and respiration

Respiration: Glucose is decomposed into pyruvate and a small amount of reducing hydrogen in the cytoplasmic matrix, after pyruvate enters the mitochondrial matrix, it reacts to generate carbon dioxide and a large amount of reducing hydrogen, which reacts with oxygen on the inner membrane of these reducing hydrogens to release energy and synthesize ATP.

Photosynthesis: 1Photoreaction stage: The thylakoid membrane in the chloroplast receives the energy of the sun to photolyze water into oxygen and reducing hydrogen, and the reducing hydrogen synthesizes ATP to provide energy for the dark reaction.

2.Dark reaction stage: After CO2 enters the chloroplast matrix, it will be fixed with C5 compounds to form C3 compounds, and C3 compounds will react with ATP to form C5 and sugars.

Differences: Respiration is carried out within the ** partichondria, photosynthesis is carried out in chloroplasts, one consumes oxygen, one releases oxygen, one consumes sugars, one emits sugars, one needs light, one does not need light.

Connection: The reactants of respiration are the products of photosynthesis.

The raw materials of photosynthesis are the products of respiration, and the raw materials of photosynthesis, the products of respiration, are just the opposite, photosynthesis needs light, and respiratory action can be done with or without light. Photosynthesis occurs in chloroplasts, and respiration occurs in the ** granula.

1. The difference between photosynthesis and respiration.

1. Different parts:

The part where photosynthesis takes place must have chloroplast cells, because chloroplasts are the structural basis for photosynthesis, figuratively likened to a "machine" for making organic matter.

Respiration is carried out by all living cells, and cells are alive to carry out normal life activities, and life activities need energy support to be completed normally, and this energy is released by the decomposition of organic matter by respiration, without respiration, cells cannot live normally, and will die.

2. The conditions are different

Photosynthesis requires light, because photosynthesis converts light energy into chemical energy and stores it in organic matter, and light energy plays a dynamic role here.

Respiration has nothing to do with light, no matter day or night, cells need energy as long as they are alive normally, and they have to rely on respiration to provide energy.

3. Different raw materials

According to the concepts of photosynthesis and respiration, it can be seen that the raw materials for photosynthesis are carbon dioxide and water.

The raw materials for respiration are organic matter and oxygen.

4. The products are different

The products of photosynthesis are organic matter and oxygen.

The products of respiration are carbon dioxide and water.

5. The energy transition is different

Photosynthesis is the production of organic matter, which converts light energy into chemical energy and stores it.

Respiration is to decompose organic matter, release the chemical energy in organic matter for life activities, and a small part is lost in the form of heat.

2. The connection between photosynthesis and respiration.

Respiration and photosynthesis are interdependent.

Without the organic matter produced by photosynthesis, respiration cannot proceed properly. This is because the organic matter decomposed by respiration is the product of photosynthesis, and the energy released by respiration is the energy stored by photosynthesis in the organic matter.

Without respiration, photosynthesis cannot proceed properly. This is because when plants are photosynthesizing, the energy required for the absorption of raw materials and the transportation of products is released by respiration.

1. The difference between photosynthesis and respiration in plants:

Photosynthesis is when plants absorb solar energy through chloroplasts, convert carbon dioxide and water into organic matter, and convert solar energy into bioenergy for storage in organic matter.

2. Place of photosynthesis: plant cell chloroplast;

Conditions of photosynthesis: light ;

Raw materials for photosynthesis: water, carbon dioxide;

Yield of photosynthesis: organic matter such as sugars;

Energy change in photosynthesis: light energy is converted into chemical energy;

3. Places of respiration: mitochondria of animal and plant cells;

Conditions of respiration: enzymes;

Raw materials for respiration: organic matter such as sugars, oxygen;

Output of respiration: carbon dioxide, water, a lot of energy;

Energy change of respiration: Stable chemical energy is transformed into active chemical energy.

1. Conditions.

Photosynthesis requires light.

Respiration can be performed with or without light.

2. Raw materials. Photosynthesis is CO2 and H20.

Respiration is C02 and organic matter.

3. Products. Photosynthesis produces organic matter (mainly starch, which is initially made up of glucose and later converted into starch, fat, protein, etc.).

Respiration produces C02 and H20.

4. Material changes.

Photosynthesis synthesizes inorganic substances (C02 and H20, etc.) into organic matter (mainly in the form of starch) and releases C02.

Respiration breaks down organic matter into inorganic matter (CO2 and H20).

5. Energy changes.

Photosynthesis absorbs light energy, converts it into chemical energy, and stores it in organic matter.

Respiration releases and converts the chemical energy stored in organic matter into various forms of energy (heat energy and all kinds of energy required for life activities).

The photosynthesis of plants provides a material basis for respiration, and respiration provides energy and raw materials for photosynthesis, they are two processes that are mutually opposed, interdependent, and mutually conditional, and coexist in a unity, without the organic matter synthesized by photosynthesis, there can be no organic matter that is decomposed by respiration and oxygen reaction, and there is no 02 released by photosynthesis, and there can be no continuous enough supply of biological respiration in the air 02, if there is no energy released by respiration, Photosynthesis is also not possible, and CO2 released by respiration is also one of the raw materials for photosynthesis.

1. Respiration: The total process of organic matter in the organism undergoes a series of oxidative decomposition in the cell, and finally produces carbon dioxide, water or other products, and releases energy, which is called respiration.

2. Photosynthesis: The process by which green plants use the light energy of the sun to assimilate carbon dioxide and water to make organic matter and release oxygen, which is called photosynthesis.

3. Difference: Respiration is carried out within the first chondrone, and photosynthesis is carried out within chloroplasts. One consumes oxygen, one emits oxygen, one consumes sugars, one emits sugars, one needs light, and one does not need light.

4. Connection: The reactants of respiration are the products of photosynthesis.

Photosynthesis: Photosynthesis usually refers to the process by which green plants (including algae) absorb light energy, synthesize carbon dioxide and water into energetic organic matter, and release oxygen at the same time. It mainly includes two stages: light reaction and dark reaction, which involves important reaction steps such as light absorption, electron transfer, photosynthetic phosphorylation, and carbon assimilation, which is of great significance for realizing the energy conversion in nature and maintaining the carbon-oxygen balance of the atmosphere. The process by which green plants use the sun's light energy to assimilate carbon dioxide (CO2) and water (H2O) to make organic matter and release oxygen is called photosynthesis.

The organic matter produced by photosynthesis is mainly carbohydrates and releases energy.
