Given a specific delta g value, you can predict whether a particular coupled chemical reaction can occur.
00:06
Examine the following three reaction and the delta g value.
00:10
So it says that which one of the following chemical reaction can occur if it's coupled with atp hydrolysis.
00:19
So first of all, you can see the first reaction atp is actually being broken down into adp plus pi.
00:29
This is an energy releasing process because you have a delta g that is a negative value, which is negative 7 .3 kcal per mole.
00:42
So this means that when molecule of atp is being broken down, it release 7 .3 kcal per mole of energy.
00:53
This is an exergonic.
01:01
Now let's look at the bottom two.
01:03
One is glucose plus pi to produce glucose 6 phosphate.
01:29
Now this one, delta g, is a positive 3 .3 k -kk -l per mole.
01:37
This one can be coupled with this first reaction here because the delta g, the energy released by hydrolyzing atp is, 7 .3 k k .m per mole.
01:51
And for this reaction to occur, you will need to require or absorb 3 .3 k .k.
02:02
Per mole of energy...
