What is respiration? what does respiration mean?
1. Aerobic respiration is the main form of respiration in higher plants, which is usually referred to as aerobic respiration. (2) anaerobic respiration refers to the process in which living cells decompose some organic compounds into incomplete oxidation products and release energy at the same time.
2. Concept: living cells use oxygen to decompose organic matter into carbon dioxide and water, and release the energy stored in the organic matter. Supply the needs of life activities, this process is called respiration.
3. Respiration is a kind of enzymatic oxidation. Although it is called oxidation, it can be called respiration with or without oxygen (because chemically, the process of electron transfer can be called oxidation).
What is the most important significance of human respiration for cellular life activities?
1. Answer Analysis: biological respiration is the process of decomposing the organic matter stored in the organism with the participation of oxygen, producing carbon dioxide and water, and releasing energy. The essence is: with the participation of oxygen, the organic matter in the mitochondria is decomposed to release energy for the use of various life activities of the organism.
2. Respiration refers to the process in which organic matter and oxygen are oxidized and decomposed into carbon dioxide and other metabolites in cells, and energy is released to meet the needs of cell life activities, so the correct answer to this question is D.
3. Hello, choose B. For organisms, respiration has a very important physiological significance, which is mainly manifested in the following two aspects: first, respiration can provide energy for the life activities of organisms. Some of the energy released by respiration is converted into heat and lost, while the other part is stored in ATP.
4. I think: among these four options, you can only choose A. Item B: the decomposition of organic matter is the role of digestive enzymes and other substances, and has nothing to do with respiration. Item C: carbohydrates, proteins and fats in three meals a day provide energy for life activities.
5. Energy. The process of respiration is divided into three stages: the first stage is in the cytoplasmic matrix, the second stage is in the mitochondrial matrix, and the third stage is in the mitochondrial intima, where oxygen and hydrogen produce water and release a lot of energy.
Respiratory essence
Respiration is carried out in cells, and its essence is to oxidize and decompose organic matter and release energy for the needs of life activities. The narrative content of item An is breathing, the content of item B is respiratory movement, and the description of item C is the gas exchange between alveolar gas and blood. So the correct answer to this question is D.
The rest is used for various life activities of plants, such as the absorption of mineral nutrients by plants, the synthesis and transport of organic matter, cell division and growth, etc., so the essence of plant respiration is to decompose organic matter and release energy. Test site: this question examines the respiration of plants.
Respiration is a chemical process in which organism cells oxidize and decompose organic matter and produce energy. The essence of respiration is that organisms decompose organic matter under aerobic or anaerobic conditions, decompose organic matter into small molecular substances, and release energy stored in organic chemical bonds.
What is respiration and its significance
The significance of respiration is to provide energy for life activities and raw materials for the synthesis of other compounds in the body. The essence of respiration is organic matter (storing energy) + oxygen → carbon dioxide + water + energy. Mitochondria in cells are the main sites of respiration and energy converters in cells.
The meaning of respiration is to provide energy for life activities. The essence of respiration is to decompose organic matter, release energy, and release carbon dioxide.
The significance of respiration: to provide reductive ability; to provide energy for plant life activities, etc.
The physiological significance of respiration is shown in two aspects: one is to provide energy for the life activities of organisms, and the other is to provide raw materials for the synthesis of other compounds in the body (such as amino acids).
The significance of respiration is to provide energy for life activities and to provide raw materials for the synthesis of other compounds in the body. Alienation refers to the process that the body degrades the molecules of organic nutrients from the environment or the cells themselves into smaller and simple end products through step-by-step reactions.
What is respiration of living things?
Respiration is a chemical process in which organisms oxidize and decompose organic matter in cells to produce energy. it is a life activity for all animals and plants. The life activities of organisms need to consume energy, which comes from the oxidative decomposition of sugars, lipids and proteins.
Respiration is a chemical process in which organism cells oxidize and decompose organic matter and produce energy. The essence of respiration is that organisms decompose organic matter under aerobic or anaerobic conditions, decompose organic matter into small molecular substances, and release energy stored in organic chemical bonds.
Respiration is a chemical process in which organisms oxidize and decompose organic matter and produce energy in cells. it is a life activity that all animals and plants have.
The essence of respiration is to decompose organic matter and release energy. Whether autotrophic or not, the energy needed to complete life activities in cells comes from respiration. Respiration is a chemical process in which organism cells oxidize and decompose organic matter and produce energy, also known as cellular respiration.
What is absorbed and released by the respiration of plants?
Plant respiration refers to the process in which plants absorb (oxygen in the air), convert the organic matter in the body into (carbon dioxide) and water, and release (energy) stored in the organic matter.
When plants breathe during the day, they absorb carbon dioxide and release oxygen. When they breathe at night, they absorb oxygen and release carbon dioxide. Plant respiration refers to the process in which plants oxidize carbohydrates, fats, proteins and other substrates under aerobic conditions to produce ATP, CO2 and water, which is contrary to photosynthesis.
Plants can absorb oxygen and it is right to release carbon dioxide gas. Plant respiration refers to the process of decomposing organic matter into carbon dioxide and water and releasing energy in the mitochondria of cells under the action of oxygen. Respiration is a kind of enzymatic oxidation.
It is true that plants can absorb oxygen and release carbon dioxide gas. Plant photosynthesis is the process in which green plants synthesize carbon dioxide and water into organic matter and release oxygen in chloroplast under light; respiration is the process in which plants decompose organic matter into carbon dioxide and water in mitochondria and release energy.
Release oxygen. Absorb oxygen and release carbon dioxide at night. Plant respiration refers to the process of oxidizing organic compounds to produce carbon dioxide and water under aerobic conditions. Plants can be divided into aerobic respiration and anaerobic respiration. The respiration of plants is carried out in cells, and the respiration of the whole plant is carried out in cells.
