What is the difference between cellular respiration and reducing hydrogen in photosynthesis

First, the converted enzymes are different.

1. The reduction of hydrogen in cellular respiration is the conversion of oxidized coenzyme 1 into reduced coenzyme 1.

2. Photosynthesis.

Medium-reduced hydrogen is the combination of coenzyme two with electrons and protons to form reduced coenzyme two.

Second, the way of breathing is different.

1. Cellular respiration is divided into fermentation, aerobic respiration, and anaerobic respiration.

Three (classified differently according to the final electron acceptor). Aerobic respiration uses molecular oxygen as the final electron acceptor, anaerobic respiration uses inorganic oxides as the final electron acceptor, and fermentation uses organic matter as the final electron acceptor. Yeast brewing, homomalced fermentation, heterolactic fermentation, etc., all belong to the category of fermentation, not anaerobic respiration.

2. Green plants use the sun's light energy to assimilate carbon dioxide.

and the process by which water makes organic matter and releases oxygen, known as photosynthesis. The organic matter produced by photosynthesis is mainly carbohydrates.

and release energy.

In cellular respiration, H] is the conversion of oxidized CoQ I (NAD) to reduced CoQ I (NaDH).

In photosynthesis, H is the combination of Coenzyme II (NaDP+) with electrons and protons (H+) to form reduced Coenzyme II (Nadph).

The hydrogen ions obtained by photolysis of water are moved from the thylakoid to the matrix outward through the protein complex on the thylakoid membrane due to the concentration difference, and the potential energy is used to synthesize ATP for dark reactions. The H ion acts as a reducing agent in the dark reaction.

The former is used to reduce CO2, the latter is used to reduce O2, the reducing agent hydrogen produced by photosynthesis is produced by decomposition of water under light, and then C3 is reduced to C5 through dark reaction, C5 reacts with CO2 into C3, and the other part of C3 reacts with water, so in the final analysis, it is to reduce CO2, and the latter is the last step of respiration to produce water with oxygen.

The former is used to reduce CO2 and the latter is used to reduce O2

The reducing agent hydrogen produced by photosynthesis is produced by splitting water under light, and then C3 is reduced to C5 through dark reaction, C5 reacts with CO2 into C3, and the other part of C3 reacts with water, so in the final analysis, it is to reduce CO2, and the latter is the last step of respiration to produce water with oxygen.

Reduced hydrogen plays the role of transferring electrons in photosynthesis.

First, the converted enzymes are different.

1. The reduction of hydrogen in cellular respiration is the conversion of oxidized coenzyme 1 into reduced coenzyme 1.

2. The reduction of hydrogen in photosynthesis is the combination of coenzyme two with electrons and protons to form reduced coenzyme two.

Second, the way of breathing is different.

1. Cellular respiration is divided into three types: fermentation, aerobic respiration, and anaerobic respiration (according to the different classification methods of the final electron acceptor). Aerobic respiration uses molecular oxygen as the final electron acceptor, anaerobic respiration uses inorganic oxides as the final electron acceptor, and fermentation uses organic matter as the final electron acceptor. Yeast brewing, homolactic acid fermentation, and heterolactic acid fermentation all belong to the category of fermentation, rather than anaerobic respiration.

2. The process by which green plants use the sun's light energy to assimilate carbon dioxide and water to make organic matter and release oxygen is called photosynthesis. The organic matter produced by photosynthesis is mainly carbohydrates and releases energy.

In contrast, the [H] produced and utilized by photosynthesis is mainly NADPH, while the [H] produced and utilized by respiration is mainly NADH and FADH. Therefore, photosynthesis is not the same as the [h] produced and utilized in respiration.

1. The generation and utilization of [h] in photosynthesis.

The process by which green plants and photosynthetic microorganisms use sunlight as an energy source and carbon dioxide as a carbon source to synthesize glucose with water and release oxygen is called photosynthesis. Photosynthesis can be divided into two stages: light reaction and carbon assimilation silver quiet reaction (formerly known as dark reaction).

During the photoreaction phase, chlorophyll and other pigments absorb light energy and store it in the form of ATP and NADPH; In the carbon assimilation stage, ATP and Nadph are used to reduce CO to produce sugars.

2. The production and utilization of [h] in respiration.

Respiration refers to the total process in which organic matter in an organism undergoes a series of oxidative decomposition in cells to eventually produce carbon dioxide or other products and release energy. The organic matter that is decomposed in respiration includes sugars, lipids, proteins, etc., and sugars are the main energy substances.

Polysaccharides and oligosaccharides are transformed into monosaccharides such as glucose by the action of corresponding hydrolase enzymes, and glucose is decomposed through several reactions to gradually release energy, and other monosaccharides can also enter the catabolic process of glucose through a certain pathway.

1. The reducing agent hydrogen produced by the aqueous action of the photosynthetic cavity is produced by decomposing water under light, and then C3 is reduced to C5 through dark reaction, C5 reacts with CO2 into C3, and the other part of C3 reacts with water.

2. So in the final analysis, it is to reduce CO2, and the latter is the last step of respiration with oxygen to produce water.

3. It is produced on the surface of the capsule-like structure film.

4. It will not work at the site of respiration, because the reduced hydrogen of photosynthesis is Nadph, and the reduced hydrogen of respiration is Nadh, and the two are not the same substance at all.
