The heart rate increases. Blood vessels supplying the muscles dilate (widen). This allows more blood containing oxygen and glucose to reach the muscles. Breathing rate and depth of breath increase.
1 of 5
How do muscles store glucose?
They store it as glycogen. Glycogen can be converted back to glucose for use during exercise.
2 of 5
Which sugar is needed by the muscles by the muscles for aerobic respiration?
Glucose.
3 of 5
Why does breathing rate and depth of breath increase during exercise?
As it allows a greater uptake of oxygen and the release of carbon dioxide at the lungs.
4 of 5
What happens to the extra carbon dioxide produced?
It needs to be removed.
