what you mean by respiration ? Types of respiration? explain.
Answers
Answer:
Explanation:
Respiration is the process in which organisms exchange gases between their body cells and the environment. From prokaryotic bacteria and archaeans to eukaryotic protists, fungi, plants, and animals, all living organisms undergo respiration. Respiration may refer to any of the three elements of the process.
2 types of respiration are as follows;
Aerobic respiration
The respiration that takes place in the presence of oxygen is called aerobic respiration because it uses ‘air’ which contains oxygen. The aerobic respiration involves utilization of oxygen for the breakdown of chemical bonds in glucose to release energy in high amounts. It is the chief source of energy for plants and animals. Animals and plants that use oxygen for respiration are aerobes. Majority of animals have aerobic respiration.
C6H12O6+6O2⟶6CO2+6H2O+Energy
All the organisms that obtain energy by aerobic respiration cannot live without the oxygen. This is because if there is no oxygen, they cannot get energy from the food which they eat. Aerobic respiration produces more energy because a complete breakdown of glucose occurs during respiration by the use of oxygen.
Anaerobic Respiration
The respiration that takes place in the absence of oxygen is anaerobic respiration. In this process, incomplete oxidation of food material is being and produces carbon dioxide and alcohol. Beside this other organic matter like citric acid, oxalic acid, lactic acid, etc are also produced.
This process is also known as intramolecular Respiration. The anaerobic respiration takes place in organisms like yeast, some bacteria, and parasitic worms. The animals and plants that can survive and obtain energy even in the absence of oxygen are called Anaerobic.
Glucose⟶Alcohol+CO2+Energy
Yeast is a single-celled fungus. In yeast, a single cell represents the whole organism. Very low amount of energy is realised in this process. Yeast respires anaerobically and during this process, yeast converts glucose into alcohol. Therefore it is used to make alcohol bread, etc.
Anaerobic respiration produces much less energy because the only partial breakdown of glucose occurs in anaerobic respiration in the absence of oxygen. All the organisms which obtain energy by anaerobic respiration can live without the oxygen.
For example, yeast is an organism which can live without the oxygen of air because it obtains energy by the process of anaerobic respiration. Yeast can survive in the absence of oxygen.
Explanation:
Respiration may be defined as bio chemical process of stepwise oxidation or breaking down of organic compounds to release energy.
Types..aerobic respiration and anaerobic respiration
Aerobic resp..when respiratory substrate is oxidized in the presence of oxygen .
anaerobic resp..when respiratory substrate is broken down in complete absence of oxygen.
