Distinguish between aerobic and anaerobic respiration.
Answers
Step-by-step explanation:
Aerobic respiration
Anaerobic respiration
Definition Aerobic respiration is a set of metabolic reactions that take place in the presence of oxygen, occurring in a cell to convert chemical energy into ATPs. Anaerobic respiration is a process of cellular respiration where the high energy electron acceptor is neither oxygen nor pyruvate derivatives.
Overall equation The overall equation of aerobic respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
The overall equation of anaerobic respiration is:
C6H12O6 → C2H5OH + CO2 + energy
Presence of Oxygen Aerobic respiration takes place in the presence of oxygen. Anaerobic respiration takes place in a condition where there is a low oxygen environment.
Exchange of gases There is an exchange of gases during aerobic respiration where oxygen is absorbed, and carbon dioxide is released. The exchange of gases doesn’t take place during anaerobic respiration. However, some gases like sulfur and nitrogen gases are released by some organisms.
Location Aerobic respiration, after glycolysis, occurs in the mitochondria of eukaryotes and cytoplasm of prokaryotes. Anaerobic respiration occurs only in the cytoplasm of a cell.
End products The end products of aerobic respiration are carbon dioxide, water, and energy. The end products of anaerobic respiration are acids, alcohols, gases, and energy.
Energy produced A total of 38 ATPs are produced during aerobic respiration, some of which are lost during the process. Only 2 ATPs are formed during anaerobic respiration.
Reactants Carbohydrates and oxygen are the prerequisites of aerobic respiration. Some other electron acceptors like sulfur and nitrogen are required along with the carbohydrates
