What are the major differences between aerobic and anaerobic metabolism? Give an example of an aerobic reaction and an anaerobic reaction
What will be an ideal response?
Aerobic reactions require oxygen; anaerobic reactions do not.
When the body needs energy quickly—as occurs when you run a quarter mile as fast as you can—pyruvate is converted to lactate. The breakdown of glucose-to-pyruvate-to-lactate proceeds without oxygen—it is anaerobic. This anaerobic pathway yields energy quickly, but it cannot be sustained for long—a couple of minutes at most.
When energy expenditure proceeds at a slower pace—as occurs when you jog around the track for an hour—pyruvate breaks down to acetyl CoA in an aerobic pathway. Aerobic pathways produce energy more slowly, but because they can be sustained for a long time, their total energy yield is greater.
