Aerobic respiration and anaerobic respiration are two different processes by which cells produce energy in the form of ATP. These processes take place in different cellular locations, including the cytoplasm and mitochondria.
In aerobic respiration, cells use oxygen to break down glucose and other organic molecules to produce ATP. This process occurs in the mitochondria, which are often referred to as the "powerhouses" of the cell. The mitochondria contain enzymes and other molecules that are necessary for the various steps of aerobic respiration, including glycolysis, the citric acid cycle, and the electron transport chain. These processes ultimately result in the production of a large amount of ATP, making aerobic respiration a highly efficient way for cells to generate energy.
On the other hand, anaerobic respiration does not require oxygen and can take place in the absence of oxygen. This process also involves the breakdown of glucose and other organic molecules to produce ATP, but it is less efficient than aerobic respiration. Anaerobic respiration occurs in the cytoplasm of the cell and involves processes such as glycolysis and fermentation. While anaerobic respiration can provide cells with a quick burst of energy in the absence of oxygen, it produces less ATP compared to aerobic respiration.
In summary, aerobic respiration takes place in the mitochondria and requires oxygen to produce a large amount of ATP, while anaerobic respiration occurs in the cytoplasm and can take place in the absence of oxygen, but produces less ATP. Both processes are essential for cells to generate energy and carry out their various functions.

Aerobic Respiration
- Location: Mitochondria
- Electron acceptor: Oxygen
- Final products: Carbon dioxide, water, ATP
- Steps:
- Glycolysis: Occurs in the cytoplasm and breaks down glucose into two molecules of pyruvic acid.
- Pyruvate oxidation: Pyruvic acid is converted into acetyl-CoA, which enters the Krebs cycle.
- Krebs cycle: Acetyl-CoA is oxidized through a series of reactions, releasing CO2 and reducing electron carriers (NADH and FADH2).
- Electron transport chain: Electron carriers shuttle electrons through a series of membrane proteins, creating a proton gradient that drives ATP synthesis.
Anaerobic Respiration
- Location: Cytoplasm (in certain organisms, like yeast and bacteria)
- Electron acceptor: Various organic molecules, such as NAD+ or sulfate
- Final products: Vary depending on the electron acceptor used (e.g., ethanol, lactic acid)
- Steps:
- Glycolysis: Same as in aerobic respiration.
- Pyruvate reduction: Pyruvic acid is reduced to a specific organic molecule using electron carriers (e.g., NADH or FADH2).
- Fermentation: The reduced organic molecule is further broken down to produce specific end products (e.g., ethanol in alcoholic fermentation).
Key Differences
| Feature | Aerobic Respiration | Anaerobic Respiration |
|---|---|---|
| Location | Mitochondria | Cytoplasm |
| Electron acceptor | Oxygen | Organic molecules |
| Final products | CO2, H2O, ATP | Organic molecule, no ATP |
| Efficiency | High (36-38 ATP per glucose) | Low (2 ATP per glucose) |
| Oxygen requirement | Requires oxygen | Does not require oxygen |
