More than that, what is respiration short answer?
Respiration is the biochemical 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 (the currency of energy in cells). ... Note the number of oxygen, carbon dioxide, and water molecules involved in each 'turn' of the process.
At any rate, what is respiration process? “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.”
Just, what is the definition of respiration in chemistry?
Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. ... aerobic, which requires oxygen and releases lots of energy.
What is the process of respiration in humans?
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.

All organisms respire to release energy to fuel their living processes. The respiration can be aerobic , which uses glucose and oxygen, or anaerobic which uses only glucose.
The process of releasing energy from food is called respiration. The process of respiration involves taking in oxygen (of air) into the cells, using it for releasing energy by burning food, and then eliminating the waste products (carbon dioxide and water) from the body.
As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
All living things get the energy they need to live from a chemical reaction called Respiration. Respiration uses oxygen and produces carbon dioxide. ... Photosynthesis uses carbon dioxide and produces oxygen.
Respiration is taking a breath or the act of breathing. An example of respiration is inhaling and exhaling air. ... The action or process of inhaling and exhaling; breathing.
Respiration is the process of gas exchange between the air and an organism's cells. Three types of respiration include internal, external, and cellular respiration. External respiration is the breathing process. It involves inhalation and exhalation of gases.
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate.
The main purpose of respiration is to provide oxygen to the cells at a rate adequate to satisfy their metabolic needs. This involves transport of oxygen from the lung to the tissues by means of the circulation of blood.
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. ... Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
Usually, this process uses oxygen, and is called aerobic respiration. It has four stages known as glycolysis, Link reaction, the Krebs cycle, and the electron transport chain.
Cellular respiration and photosynthesis are biological processes in which matter and energy flow through the biosphere. These two processes are responsible for the exchange of oxygen and carbon dioxide between living organisms and the environment.
Step 3: Aerobic respiration Organisms release energy from food (glucose), as well as carbon dioxide and water in the process of aerobic respiration. This energy is used to do the work needed to keep cells and organisms alive. Aerobic respiration requires oxygen.
Alveoli are the tiny air sacs (only 1 cell thick) in the lungs at the end of the smallest airways, where the exchange of oxygen and carbon dioxide takes place.
Glycolysis is the process in which glucose is broken down to produce energy. It produces two molecules of pyruvate, ATP, NADH and water. The process takes place in the cytosol of the cell cytoplasm, in the presence or absence of oxygen. Glycolysis is the primary step of cellular respiration.
Respiratory muscles The diaphragm, a dome-shaped sheet of muscle that separates the chest cavity from the abdomen, is the most important muscle used for breathing in (called inhalation or inspiration). The diaphragm is attached to the base of the sternum, the lower parts of the rib cage, and the spine.
The rate and depth of breathing is automatically controlled by the respiratory centers that receive information from the peripheral and central chemoreceptors. These chemoreceptors continuously monitor the partial pressures of carbon dioxide and oxygen in the arterial blood.
The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process, where the synthesis of organic compounds occurs, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.
