Exercise Flashcards
When you exercise what do your muscles get more of
Oxygen and glucose
An increase in muscle activity requires more…
Glucose and oxygen to be supplied to the muscle cells
What does physical activity do
Increases the breathing rate.. Makes you breathe more deeply to meet demand for extra oxygen
Increases the speed at which the heart pumps
What is glucose from food stored as
Glycogen
Where is glycogen mainly stored
I’m the liver, but each muscle has its own store
During vigorous exercise muscles use glucose rapidly.. What happens to the gulch gem stored
The glycogen is converted back to glucose ro proved more energy
When is anaerobic respiration used
When there is not enough oxygen
When does your body do anaerobic respiration instead of aerobic respiration
When you do vigorous exercise and your body can’t supply enough oxygen to your muscles
What does anaerobic mean
Without oxygen
What is anaerobic
The incomplete breakdown of glucose
What does anaerobic respiration produce
Lactic acid
Why is anaerobic respiration not the best way of converting glucose into energy
Because lactic acid builds up in the muscles and it causes muscle fatigue
What is a disadvantage of anaerobic respiration
It does not release much energy unlike aerobic respiration
A advantage of anaerobic respiration
It helps you keep using your muscles for longer
What does anaerobic respiration lead to
An oxygen debt
