Question

What are the differences between aerobic and anaerobic respiration? Name some organisms that use the anaerobic mode of respiration.

Answer 1

Hint: Both aerobic and anaerobic respiration releases carbon dioxide as one of the end products but the other one is different that is water in aerobic and ethanol in anaerobic. Similarly, they bear many other differences.

Complete answer:

Aerobic respiration	Anaerobic respiration
Aerobic respiration is a metabolic process that takes place in the presence of oxygen in a cell to convert chemical energy into ATPs.	Anaerobic respiration is a process of cellular respiration that takes place in the absence of oxygen.
The carbon dioxide and water is the end product of aerobic respiration.	Ethanol and carbon dioxide is the end product of anaerobic respiration.
During aerobic respiration, a high amount of energy is released as compared to anaerobic respiration.	During anaerobic respiration, less energy is released as compared to aerobic respiration.
The process of aerobic respiration takes place in the cytoplasm and mitochondria of the cell.	The process of anaerobic respiration takes place only in the cytoplasm of the cell.
Complete oxidation of glucose takes place during aerobic respiration.	Incomplete oxidation of glucose takes place during anaerobic respiration.
Aerobic respiration includes the exchange of gases between the organism and the outside environment.	In anaerobic respiration exchange of gases is absent.
Aerobic respiration occurs in all higher organisms such as mammals	Anaerobic respiration occurs in lower organisms such as lactic acid bacteria, E. Coli, staphylococcus, clostridium, yeast, etc.

Note:
- To provide carbon dioxide and water glucose and oxygen react collectively in cells and release energy in aerobic respiration.
- The by-product of initial and aerobic glycolysis is oxidized to provide carbon dioxide water and plenty of energy (ATP molecules).
- In anaerobic respiration, the electron acceptor is neither oxygen nor pyruvate derivatives.
