Exercise Flashcards
Why does the rate of blood flow increase with an incense in the intensity of exercise?
- to supply more glucose and oxygen
- to remove excess carbon dioxide
Why does your breathing rate increase during exercise?
To meet the demand for more oxygen
What is the purpose of glycogen?
It is converted back to glucose to provide more energy during exercise
What is anaerobic respiration?
Respiration without oxygen
When does anaerobic respiration occur?
When there is not enough oxygen for aerobic respiration
What is the equation for anaerobic respiration?
Glucose -> energy + lactic acid
What causes muscle fatigue?
A build up of lactic acid in the muscles
Does aerobic or anaerobic respiration produce more energy?
Aerobic
What is an oxygen debt?
Where you have to get lots of oxygen into your blood after exercise in order to break up lactic acid into carbon dioxide and water
What happens to the rate of blood flow when the intensity of exercise increases?
It increase
