Okay, one to answer the question, let's talk about energy.
00:05
Okay, so energy, remember that it can be transferred.
00:09
It can be transferred.
00:12
And also it can't be created, okay? you can't create new energy.
00:19
This transfer of energy is always inefficient.
00:22
It is always inefficient and why? because some energy, always, some energy is going to be lost as heat.
00:31
Also, the free energy is the energy, available to do work, okay? the free energy is that energy available to do work.
00:43
And there are two types of chemical reactions.
00:45
We have ersegonic reactions that proceed with a net release of free energy, okay? net release of free energy.
00:59
And also we have endergonic reactions that particularly absorbed free energy.
01:12
Okay, so practically these are the two types of energy or reaction that we're going to have.
01:18
For example, talking about extrambonic reactions, remember that this is atp, okay? let's suppose this is atp...
