How is the oxygen debt paid?
Blood flowing through muscles transports lactic acid to liver where it is converted back to glucose.
What is the word equation for anaerobic respiration?
Glucose to lactic acid
What are 2 reasons we do not use anaerobic respiration?
Incomplete breakdown of oxygen, making it inefficient and lactic acid builds up which needs to be removed
What is the word equation for anaerobic respiration in plants?
Glucose to carbon dioxide and ethanol
