Hi there.
00:03
This question is asking about chemical energy.
00:12
Chemical energy is often also known as chemical potential energy.
00:25
Because it is energy that is stored in chemical compounds.
00:52
And this energy can be released through chemical reactions.
01:09
In other words, the breaking and reforming of bonds.
01:13
Because that energy is actually stored in those chemical bonds.
01:16
So if we can break those and reform them with lower energy bonds, then that energy is released.
01:30
We can think about photosynthesis, for example.
01:33
Photosynthesis is the process by which the energy from the sun is used to take carbon dioxide in water and make a glucose molecule.
01:43
So that energy from the sun is stored in the bonds of the glucose.
01:47
To harvest that, cells undergo cellular respiration, where they're going to be.
01:52
Break that glucose molecule back down to release that energy...
