What is a respiration in science?

“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 for example?

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 respiration in biology easy?

Respiration is a chemical reaction which occurs in all living cells, releasing energy from glucose. Aerobic respiration occurs with oxygen and releases more energy but more slowly.

What is respiration very short answer?

1 : the act or process of breathing : the inhaling of oxygen and the exhaling of carbon dioxide. 2 : the process by which cells use oxygen to break down sugar and obtain energy. respiration.

What is a respiration in science? – Related Questions

What is respiration simple answer?

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 is respiration for Class 7th?

The process of breakdown of food in the cell with the release of energy is called cellular respiration. Cellular respiration takes place in the cells of all organisms. In the cell, the food (glucose) is broken down into carbon dioxide and water using oxygen.

What is the respiration Class 8?

Respiration is the process of obtaining energy by combining oxygen and glucose, and release of carbon-di-oxide, water and ATP.

What is respiration 5th standard?

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 respiration BYJU’s?

Respiration is the process through which living organisms take in oxygen and give out carbon dioxide to release energy. So, naturally, respiration is a major and vital process of gas exchange. The transport of gases during respiration, both oxygen and carbon dioxide are carried out by the blood cells.

What is respiration and types?

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.

What are the 4 types of respiration?

Respiration consists of 4 distinct processes:
  • Pulmonary Ventilation. moving air into and out of the lungs.
  • External Respiration.
  • Transport. transport of oxygen and carbon dioxide between the lungs and tissues.
  • Internal Respiration. diffusion of gases between the blood of the systemic capillaries and cells.

Why is respiration needed?

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.

What is the result of respiration?

Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is: In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

Where does the respiration occur?

Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell’s cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

Does respiration release energy?

Respiration is the chemical process by which organic compounds release energy. The compounds change into different ones by exergonic reactions. The hydrolysis of adenosine triphosphate (ATP) to adenosine diphosphate (ADP) and phosphoric acid (Pi) releases energy (it is an exergonic reaction).

Which gas is used for respiration?

Respiration is the movement of oxygen from the outside environment to the cells within tissues, and the removal of carbon dioxide in the opposite direction. In respiration, the oxygen liberated by plants is used by the body to produce energy.

What is the first stage of respiration?

Glycolysis: The Foundation of Cellular Respiration

Glycolysis, the first step of cellular respiration, occurs in the cytoplasm of your cells. During this process, a glucose molecule is broken down into two molecules of pyruvate (pyruvic acid).

What are the two types of respiration?

The two types of respiration are aerobic respiration ( it is a process that uses oxygen) and anaerobic respiration ( it is a process that doesn’t use oxygen).

What is the other name of respiration?

In this page you can discover 22 synonyms, antonyms, idiomatic expressions, and related words for respiration, like: breath, breathing, exhalation, inhalation, process, cellular respiration, expiration, ventilation, external respiration, internal respiration and peristalsis.

What is respiration without oxygen called?

Respiration without oxygen is anaerobic respiration. It is called fermentation. Fermentation takes place in various prokaryotes, and unicellular eukaryotes. Lactic acid fermentation also takes place in muscle cells.

What are the 5 steps of respiration?

Respiration involves 5 basic steps and the correct order of them
  • A. Pulmonary ventilation ⇒ External respiration ⇒ Transport of gases ⇒ Internal respiration ⇒ Cellular respiration.
  • B. Internal respiration ⇒ Cellular respiration ⇒ Pulmonary ventilation ⇒ External respiration ⇒ Transport of gases.
  • C.
  • D.
