Under aerobic conditions, carbohydrates, fats, protein and other substrates are oxidized to produce ATP and co? The process of mixing water and water is opposite to photosynthesis. When the oxygen supply of plant tissue is insufficient or anoxic, the organic matter in it can be partially decomposed to produce a small amount of co? And release a small amount of energy. This is fermentation, sometimes called anaerobic respiration.

Extended data:

Temperature can affect respiration, mainly affecting the activity of respiratory enzymes. Generally speaking, in a certain temperature range, the respiratory intensity increases with the increase of temperature.

According to the influence principle of temperature on respiratory intensity, the temperature should be lowered when storing vegetables and fruits in production practice to reduce respiratory consumption. The degree of cooling is based on the premise of not destroying plant tissues, otherwise cells will be damaged, the resistance to pathogenic microorganisms will be greatly reduced, and it is easy to rot and damage.

Although plants rely on photosynthesis to provide energy to form organic matter, non-green parts (and green parts in the dark) release chemical energy in photosynthetic products through respiration, which is used in various physiological activities in the form of high-energy bonds in ATP. Its basic reaction is similar to that of animals and microorganisms, and electron transfer and phosphorylation are also carried out on mitochondria.

Different from higher animals, plants have flat and thin leaves, numerous stomata, and are easy to exchange with atmospheric gas. Except swamp plants such as rice, there are no respiratory organs such as lungs and gills.

The respiration rate varies with plant species, developmental stages and physiological states. The respiratory rate of young and vigorous growing tissues is high, while that of mature and aging tissues is low. The respiratory rate of reproductive organs is higher than that of vegetative organs. The most important environmental factors affecting respiratory rate are temperature, atmospheric composition, humidity and light.
