Question

why aerobic respiration is more efficient than anaerobic respiration

Answer 1

because it takes place in the presence of oxygen and occcurs in mitochondria. End products are CO2 and H2O

Answer 2

Answer:

The most significant reason is that in aerobic respiration, a large amount of energy (36-38 ATP) is released while on the other hand energy released is much lower in anaerobic respiration (2 ATP).

Explanation:

• There are many more reasons to claim this efficiency like aerobic respiration requires oxygen but anaerobic respiration occurs without oxygen.
• Carbon dioxide, water and ATP (36-38) are products of aerobic respiration but in case of anaerobic respiration, along with carbon dioxide and ATP (2) some reduced species are also formed as products like ethanol and lactic acid.
• Mitochondria (power house of the cell) is the site for aerobic respiration but cytoplasm is the site for anaerobic.
• Aerobic respiration is a result of complete combustion of reactants while anaerobic is because of incomplete combustion.
• Aerobic respiration uses ETC ( Electron transport chain) and use oxygen as electron acceptor but this is not the case in anaerobic respiration.
• Aerobic respiration occurs in almost all the cells but anaerobic respiration is confined to prokaryotic cells and in muscle cells under certain conditions.
