A quick lesson on how your cells turn food into energy.
Current design scheme: Ocean
Sugar plus oxygen produces carbon dioxide, water, and usable energy. This is how your cells make ATP, the molecule they use for power.
One glucose molecule is split into two smaller molecules, producing a little bit of ATP.
The smaller molecules are broken down further inside the mitochondria, releasing carbon dioxide.
This final stage produces the most ATP of all three stages, around 34 molecules per glucose.
Without oxygen, cells can only make a small amount of energy through a backup process called fermentation.
