Aerobic respiration produces a considerable amount of energy for use by the organism which gets stored in the ATP molecules. Examples for aerobic respiration are all multicellular organisms like birds, animals, insects, humans etc.

What is anaerobic and aerobic respiration?
Aerobic respiration is a fixed metabolic reaction that takes place in the presence of oxygen, going on in a cell to transform chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration in which the excessive energy electron acceptor is neither oxygen nor pyruvate derivatives.
What is aerobic in general biology?
Definition. adjective. (1) Of, pertaining to, having, or requiring the presence of air or free oxygen. (2) (biology) Requiring air or oxygen for life or survival, used especially to refer to aerobic bacteria.
Why is it called aerobic respiration?
Respiration using oxygen to break down food molecules is called aerobic respiration . ‘Aero’ means air, which contains oxygen, leading to the name aerobic respiration. Glucose is the molecule normally used for respiration – it is the main respiratory substrate .
What is anaerobic respiration simple?
Anaerobic respiration occurs without oxygen and releases less energy but more quickly than aerobic respiration. Anaerobic respiration in microorganisms is called fermentation.
What is use of aerobic respiration?
Aerobic respiration provides energy to fuel all cellular processes. The reactions produce ATP, which is then used to power other life-sustaining functions, including growth, repair, and maintenance.
What is aerobic process?
An aerobic process refers to a process that requires the presence of oxygen or air as opposed to an anaerobic process that does not require it. An example of an aerobic process is aerobic respiration. The biological cell conducts respiration in a process called cellular respiration.
What is the difference between aerobic and anaerobic organisms?
An aerobic organism or aerobe is an organism that can survive and grow in an oxygenated environment. In contrast, an anaerobic organism (anaerobe) is any organism that does not require oxygen for growth. Some anaerobes react negatively or even die if oxygen is present.
What are the main steps of aerobic respiration?
Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis.
What are the 3 stages of aerobic respiration?
The three stages of aerobic cellular respiration are glycolysis (an anaerobic process), the Krebs cycle, and oxidative phosphorylation.
What are the 5 stages of aerobic respiration?
In order for aerobic respiration to occur, the 5 stages that have to take place are glycolysis, oxidation of pyruvate, Krebs’s cycle, electron transport chain, and chemiosmosis (Notes, 10/5/15). Glycolysis is the splitting down of the sugar molecules into 2 3-carbon molecules.
Who discovered aerobic respiration?
Krebs discovered the mechanism of aerobic respiration.
Where does aerobic respiration occur?
While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
What are the 4 types of respiration?
- 3.1 Aerobic respiration.
- 3.2 Anaerobic Respiration.
- 3.3 Anaerobic Respiration in Muscles.
- 3.4 Aerobic versus Anaerobic Respiration.
- 3.5 Similarities Between Aerobic and Anaerobic Respiration.
What is anaerobic respiration also known as?
The other name for anaerobic respiration is fermentation. Anaerobic respiration is a type of cellular respiration, which occurs in the absence of oxygen. Fermentation is an anaerobic process, which occurs within various cells such as yeast cells, bacteria, muscle cells, etc. Explore More: Fermentation.
What is anaerobic in biology?
The word anaerobic indicates “without oxygen.” The term has many uses in medicine. Anaerobic bacteria are germs that can survive and grow where there is no oxygen. For example, it can thrive in human tissue that is injured and does not have oxygen-rich blood flowing to it.
Why is respiration anaerobic?
Anaerobic respiration is useful in generating electricity in microbial fuel cells, which employ bacteria that respire solid electron acceptors (such as oxidized iron) to transfer electrons from reduced compounds to an electrode. This process can simultaneously degrade organic carbon waste and generate electricity.
What is aerobic respiration Class 11?
Aerobic respiration is the process in which complex organic macromolecules are broken down into simpler substances in presence of oxygen, and energy is released along with the production of carbon dioxide and water.โ Glucose + Oxygenn โ Carbon dioxide + Water + Energy.
What is aerobic and anaerobic with example?
Examples of aerobic exercise include swimming laps, running, or cycling. Anaerobic exercises involve quick bursts of energy and are performed at maximum effort for a short time. Examples include jumping, sprinting, or heavy weight lifting.
Which process is anaerobic?
Anaerobic respiration is the process of creating energy without the presence of oxygen. Sometimes the body cannot supply the muscles with the oxygen it needs to create energy, for example during intense exercise.
Are plants aerobic or anaerobic?
Plant cells do not have mitochondria and therefore cannot respire using aerobic respiration. Anaerobic respiration occurs in the cytoplasm, therefore plants do experience anaerobic respiration.
How much ATP is produced in aerobic respiration?
Theoretically, 38 ATP molecules can be produced by the complete oxidation of one glucose molecule in aerobic respiration.
What are the two types of aerobic respiration?
Anaerobic Respiration. Aerobic respiration, a process that uses oxygen, and anaerobic respiration, a process that doesn’t use oxygen, are two forms of cellular respiration. Although some cells may engage in just one type of respiration, most cells use both types, depending on an organism’s needs.
How ATP is formed?
ATP is also formed from the process of cellular respiration in the mitochondria of a cell. This can be through aerobic respiration, which requires oxygen, or anaerobic respiration, which does not. Aerobic respiration produces ATP (along with carbon dioxide and water) from glucose and oxygen.
What is the word equation for aerobic respiration?
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 โ 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water). Was this answer helpful?
