Answer 3

ATP is what the cells in your muscles use for energy.
Oxygen is needed to breakdown glucose and create ATP.

Muscles store glucose as glycogen in your muscles. Typically, your muscles have more glycogen than oxygen, so oxygen becomes the limiting factor in creating ATP.

Muscles store oxygen as well using a protein called myoglobin. By storing oxygen, myoglobin allows muscles to have more oxygen available to them than other cells in your body.
