Respiration Respiration is a series of exothermic reactions that occur in the mitochondria of living cells in order to release energy from food molecules. This energy can then be used to produce heat, for movement, growth, reproduction and active uptake.
What is respiration in biology simple?
“Respiration is defined as a metabolic process wherein, the living cells of an organism obtains energy (in the form of ATP) by taking in oxygen and liberating carbon dioxide from the oxidation of complex organic substances.”
What is respiration easy words?
The transfer of oxygen from the outside environment to cells within tissues, as well as the removal of carbon dioxide in the opposite way, is referred to as respiration.
What is respiration kid friendly definition?
Respiration is the process that all living things go through to create the energy they need to live. This happens in the cells so it is also called cellular respiration. It usually involves exchanging two gases—oxygen and carbon dioxide. The cells take in oxygen and release carbon dioxide.
What is the best explanation of respiration?
The word respiration is commonly used to describe the process of breathing in oxygen and breathing out carbon dioxide. However, the term more formally refers to the chemical process organisms use to release the energy from food, which typically involves the consumption of oxygen and release of carbon dioxide.
What is respiration answer in one sentence?
Respiration is the process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide, water, and ATP (energy).
What are the 3 processes of respiration?
There are three main steps of cellular respiration: glycolysis, the citric acid cycle, and oxidative phosphorylation. Glycolysis takes place in the cytosol, the citric acid cycle occurs in the mitochondrial matrix, and oxidative phosphorylation occurs on the inner mitochondrial membrane.
What are the 4 processes of respiration?
The processes of the respiratory system are pulmonary ventilation, external respiration, transport of gases, internal respiration, and cellular respiration.
What type of process is respiration?
Respiration is a catabolic process. In respiration, glucose breakdown to form ATP (energy).
What is respiration for primary school?
Respiration is the process in which living things take in oxygen to break down digested food and produce energy. During respiration, carbon dioxide is given out.
What are the 5 main functions of the respiratory system?
The functions of the respiratory system include gas exchange, acid-base balance, phonation, pulmonary defense and metabolism, and the handling of bioactive materials.
Which is an example of respiration?
Respiration is taking a breath or the act of breathing. An example of respiration is inhaling and exhaling air.
What are the two steps of respiration?
Different steps involved in the process of respiration are :Breathing or pulmonary ventilation by which outside air is inhaled and carbon dioxide-rich air is exhaled.Diffusion of gases occurs across the alveolar membrane.Gaseous transport occurs through the blood.More items...
What is respiration and example?
breathing, which is the process of inhaling and exhaling gases from and into the external environment – a function of the lungs and other structures with similar function (e.g. gills)
What's an example of respiration?
Respiration is taking a breath or the act of breathing. An example of respiration is inhaling and exhaling air. Any similar process, in organisms that lack lungs, that exchanges gases with its environment. The process of inhaling and exhaling; breathing, breath.
What is respiratory example?
The organs that are involved in breathing. These include the nose, throat, larynx, trachea, bronchi, and lungs. Also called respiratory tract. Anatomy of the respiratory system showing the trachea, the right and left lungs and their lobes, and the bronchi.
What is respiration in human?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.

Where does respiration take place?
Respiration is the process that releases energy in cells from glucose. This process takes place in the mitochondria. So, respiration happens in both animals and plants because they both have mitochondria.
What is the difference between respiration and photosynthesis?
In photosynthesis, plants take in carbon dioxide and water than produce glucose and oxygen. Which means the glucose and oxygen made in photosynthesis is used for respiration.
What is the reaction between glucose and oxygen?
Or in other words, glucose is reacting with oxygen to form carbon dioxide and water. This reaction releases energy, so sometimes the equation may show energy in brackets.
Where does photosynthesis take place?
Plant respiration takes place in the dark and in the light. However, photosynthesis only takes place in the light.
