All right, so in this question we're being asked about the metabolic processes and which of these equations down here can occur without the influx of energy from other processes.
00:14
So what we're going to want to know is what an endergonic reaction is.
00:18
An endergonic reaction is something is one that occurs in which energy is absorbed.
00:23
So looking at this graph here, we're going to draw it out.
00:27
Usually it means that there is more energy at the end.
00:31
You see, at the end of the reaction here.
00:35
So this is where the products are.
00:41
This is where the reactants are.
00:47
And so it's saying that at the end of the reaction, this here will have more energy than what went into the reaction.
00:55
Therefore, energy is being absorbed.
01:00
So when we're looking at this problem here, these are all the options, a, b, c, d, and e, out of order, of course.
01:09
We are going to look at this one here first.
01:12
So looking at adp, identicing diphosphate, plus a phosphate, is actually an endergonic reaction in which it consumes energy in order to reach atp...
