What is the purpose of increased breathing rate during exercise?
To take in more oxygen for aerobic respiration and exhale more carbon dioxide
What happens to glycogen during increased physical activity?
Glycogen is converted to glucose
What is meant by "insufficient oxygen" during exercise?
It refers to the lack of oxygen available for aerobic respiration
What happens to heart rate after exercise?
Heart rate slowly decreases
What is "oxygen debt"?
It is the amount of oxygen needed to break down lactic acid
Why is oxygen needed to react with lactic acid?
To remove lactic acid from cells
Where is some lactic acid transported after exercise?
To the liver
What happens to lactic acid in the liver?
It is converted back to glucose
What are the physiological changes during and after exercise?
Increased breathing rate for more oxygen intake
Conversion of glycogen to glucose
Insufficient oxygen for aerobic respiration
Heart rate decreases after exercise
Oxygen debt occurs to break down lactic acid
Lactic acid is transported to the liver for conversion back to glucose
