Aerobic respiration

Why?

Aerobic respiration uses oxygen to release energy from glucose, giving carbon dioxide and water.

A glucose molecule and six oxygen molecules enter a mitochondrion and out come six carbon dioxide, six water and a burst of energy.

Press the button to send glucose and oxygen into a mitochondrion.

Drag the picture to look around.

A runner's breathing speeds up to bring in more oxygen for respiration in her leg muscle cells.
