We are being asked to identify which term describes the sum of all the chemical reactions in a cell.
00:10
So the two keywords that we want to look at here is that it's a sum of reactions and that it occurs in a cell.
00:18
So the term that we're looking for needs to satisfy both of these criteria.
00:24
So let's look at what kind of reactions happen in the cell.
00:28
And basically, in a nutshell, you're dealing with nutrient breakdown.
00:32
Atp synthesis and building of new molecules.
00:36
So the collection of chemical reactions that happen in a cell, what is it called? let's look at our answer choices here.
00:44
Free energy, which can be denoted by g or gives free energy named after gives, right? it is the amount of energy available for work.
01:02
So, for example, benzene has energy in it and it can be harnessed.
01:17
Well, that says nothing about a cell.
01:20
That can occur completely outside of the cell.
01:23
So this cannot be our choice.
01:28
The second choice is, and you can think of entropy for our purposes as basically a measure of disorder.
01:43
So basically when you go from ordered room to messy room, you say that entropy has increased, right? again, this has nothing to do with cells...
