All right, so when you're considering how everything you're learning plays into thermodynamics, i think it's most important to look at the first law, which states that energy can neither be created nor destroyed, only transferred between states.
00:15
So energy isn't created or destroyed, only transferred.
00:34
And let's look at a quick example of this.
00:37
Let's just take a look at the synthesis of atp from adp and phosphate.
00:42
We know that these reactants are a lower energy state.
00:47
Atp is then synthesized, a higher energy molecule.
00:52
And then this same atp is later broken down, hydrolyzed, into adp, and phosphate, and then some energy.
01:03
And this energy can be used to perform work, but a lot is actually lost as heat.
01:08
And so we see that the energy isn't created or destroyed...
