The bonds that hold glucose and other food molecules together contain chemical energy.

Here's why:

* Chemical bonds store energy: Chemical bonds represent the potential energy stored within the arrangement of atoms in a molecule.

* Breaking bonds releases energy: When these bonds are broken, like during digestion, the stored energy is released.

* This energy is used by cells: Cells then use this released energy to perform various functions, like building new molecules, moving, or generating heat.

So, the bonds in food molecules are like tiny packets of energy that our bodies can access by breaking them.
