Final answer:
Aerobic respiration occurs in the presence of oxygen and produces more ATP compared to anaerobic respiration. We prefer not to use anaerobic respiration due to its lower energy efficiency and the production of toxic waste products.
Step-by-step explanation:
Aerobic respiration occurs in the presence of oxygen, while anaerobic respiration occurs in the absence of oxygen. One of the main differences is the amount of energy (ATP) produced.
Aerobic respiration produces much more ATP compared to anaerobic respiration.
There are two main reasons why we prefer not to use anaerobic respiration:
Energy Efficiency: Aerobic respiration produces more ATP, which is the energy currency of cells.
This allows cells to perform their functions more efficiently.
Waste Products: Anaerobic respiration produces waste products such as lactic acid or ethanol, which can be toxic to cells and can lead to an accumulation of waste that impairs cellular function.
