Difference between aerobic respiration and anaerobic respiration:

You have already learned about aerobic and anaerobic respiration and even you know that these two processes are similar in various terms. In this article, we are going to discuss what is aerobic respiration, what is Anaerobic respiration, and What's the difference between aerobic and anaerobic respiration. 

The first stage of the two reactions is the same, that is, glucose is decomposed into pyruvate, reduced hydrogen, and ATP under the catalysis of enzymes. Aerobic respiration is mainly in the mitochondria, while anaerobic respiration is mainly in the cell matrix. 

Aerobic respiration requires the participation of molecular oxygen, while anaerobic respiration does not require the participation of molecular oxygen. 

The decomposition products of aerobic respiration are carbon dioxide and water, and the decomposition products of anaerobic respiration are alcohol or lactic acid. Aerobic respiration releases more energy, while anaerobic respiration releases less energy.

Aerobic respiration is a cellular respiration that takes place in the presence of oxygen to produce energy from food is called aerobic respiration.

Anaerobic respiration is biochemical process in which cells can break down sugars to generate energy in absence of oxygen.

Similarities between Aerobic and Anaerobic Respiration:

• Both aerobic and anaerobic respiration are biochemical processes by which cells obtain energy from glucose molecules.
• Both processes involve the breakdown of glucose into smaller molecules, such as pyruvate, through glycolysis.
• Both biochemical processes generate ATP, the energy currency of the cell, which is used to power cellular activities.
• Both Aerobic and Anaerobic Respiration occur in the cytoplasm of cells, where glycolysis takes place.
• Both Aerobic and Anaerobic Respiration involve the conversion of NADH back to NAD+ to continue the glycolytic pathway.

What is the Difference between Aerobic and Anaerobic Respiration

Aerobic respiration	Anaerobic respiration
Aerobic respiration is a cellular respiration that takes place in the presence of oxygen to produce energy from food is called aerobic respiration.	Anaerobic respiration is the process of cellular respiration that takes place in the absence of oxygen to produce energy from food.
Oxygen is present when this form of respiration takes place	Oxygen is absent when this form of respiration takes place
It can be found in the cytoplasm and the mitochondria	It can be found only in the cytoplasm
Glucose breaks down into carbon dioxide and water	Glucose breaks down into carbon dioxide, ethyl alcohol, and energy
It involves the exchange of gases between the organisms and the outside environment	In anaerobic respiration exchange of gases is absent
Aerobic respiration takes a longer time to release energy.	It is a fast process as compared to aerobic respiration.
In aerobic respiration, glucose is completely oxidized to CO2 and H2O.	In Anaerobic respiration, glucose is incompletely oxidized to either an organic acid or alcohol with CO2.
In aerobic respiration, a high amount of energy is produced	In anaerobic respiration, less amount of energy is produced
A net gain of 36 molecules of ATP occurs.	A net gain of only 2 molecules of ATP occurs
All higher organisms such as mammals have this type of respiration	Lower organisms such as bacteria and yeast are this type of respiration.
The end products of aerobic respiration are CO2 and water.	The end product of anaerobic respiration can be lactic acid or CO2 and Alcohol.

Difference between Aerobic and anaerobic respiration

Write the difference between aerobic and anaerobic respiration with examples:

The first stage of the two reactions is the same, that is, glucose is decomposed into pyruvate, reduced hydrogen, and ATP under the catalysis of enzymes.

• Different properties: anaerobic respiration is a special type of respiration with low productivity that occurs when anaerobic or facultative anaerobic microorganisms use exogenous inorganic oxides or organics as terminal hydrogen (electron) acceptors under anaerobic conditions. Aerobic respiration refers to the process that cells, with the participation of oxygen, through the catalysis of various enzymes, completely oxidize and decompose organic matter, generate carbon dioxide and water, release energy, and synthesize a large amount of ATP.

• Different characteristics: Aerobic respiration is the main form of respiration for higher animals and plants. Anaerobic respiration is a kind of biological oxidation in which the hydrogen acceptor at the end of the respiratory chain is exogenous inorganic oxides (individually organic oxides).

• Different stages: aerobic respiration is divided into three stages. The third stage involves the participation of oxygen, which completely decomposes the organic matter and releases a lot of energy. Anaerobic respiration is divided into two stages. Without the participation of oxygen, the organic matter is not completely decomposed.

• Necessary conditions: aerobic respiration requires the participation of oxygen and enzymes, and anaerobic respiration only requires enzymes.

• Location: aerobic respiration is in the cytoplasmic matrix and mitochondria; anaerobic respiration is mainly in the cytoplasmic matrix.

• Reaction formula: aerobic C6H12O6+6H2O+6O2→6CO2+12H2O+a lot of energy; Anaerobic C6H12O6+enzyme→2C3H6O3(lactic acid)+a small amount of energy or C6H12O6+enzyme→2C2H5OH(ethanol)+2CO2+a small amount of energy.

FAQs on the Difference between Aerobic and Anaerobic Respiration:

1. What are Similarities between Aerobic and Anaerobic Glycolysis?

Answer: 

• Both aerobic and anaerobic glycolysis begin with the breakdown of glucose into two molecules of pyruvate.
• Both processes occur in the cytoplasm of cells.
• Both processes involve the conversion of NAD+ to NADH during glycolysis.
• Both processes produce a net gain of ATP through substrate-level phosphorylation.
• Both aerobic and anaerobic glycolysis serve as the initial stage of energy production in cellular respiration.

2. What is the difference between aerobic and anaerobic respiration?

Answer: 

Aerobic Respiration: 

• Aerobic Respiration takes place in the presence of oxygen. 
• In Aerobic respiration, glucose breaks down or completely oxidation into carbon dioxide and water.
• It produces a greater amount of energy.
• Occurs in higher organisms such as mammals.
• In aerobic respiration the last hydrogen acceptor is oxygen, and therefore water is the end product of oxidation.

Anaerobic Respiration: 

• Anaerobic Respiration takes place in the absence of oxygen.
• In anaerobic respiration, glucose breaks down into ethyl alcohol, carbon dioxide, and energy.
• Lesser energy is produced during this process.
• Occurs in lower organisms such as bacteria and yeast.
• During anaerobic respiration, the last hydrogen acceptors include other substances formed during the fermentation of the substrate.

3. What are 3 similarities between anaerobic and aerobic respiration?

Answer: 

• In both aerobic and anaerobic respiration, the food is broken down to release energy.
• Both respiration and respiration occur inside the cells.
• Both supply by-products.
• Both use glucose as the starting molecule.

4. What is an anaerobic respiration example?

Answer: Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation, and in decomposition of organic matter.

5. How much ATP is produced during aerobic respiration?

Answer: Aerobic respiration generates 38 ATP molecules for every oxidized glucose molecule. The total amount of energy released during the complete oxidation of glucose is 2880 kJ per 1 mol.

6. What about Anaerobes?

Answer: Anaerobes include some types of bacteria, yeast, protozoa, and worms. The term anaerobes. was introduced by Louis Pasteur, who discovered microbes of butyric fermentation (1861). Anaerobes are divided into obligate and facultative. Obligate anaerobes are also called obligate or strict anaerobes.
