The Difference in ATP Production
* Aerobic Respiration: This process utilizes oxygen and yields a substantial amount of ATP (adenosine triphosphate), the primary energy currency of cells. It breaks down glucose to produce around 36-38 ATP molecules per glucose molecule.
* Anaerobic Respiration: This process occurs in the absence of oxygen and is less efficient. It produces only 2 ATP molecules per glucose molecule.
The Calculation
To produce the same amount of ATP as aerobic respiration (let's assume 38 ATP), you would need to process:
38 ATP (aerobic) / 2 ATP (anaerobic) = 19 times more glucose
In Conclusion
An eukaryotic cell would need to process 19 times more glucose through anaerobic respiration to produce the same amount of energy as aerobic respiration. This is because anaerobic respiration is much less efficient at extracting energy from glucose.
