Hi, my name's michaela.
00:03
I'm going to help you through this problem.
00:05
So this wants us to answer a question about how the creation of an atp molecule from adp plus inorganic phosphate can drive cellular work.
00:26
So let's talk about this really fast.
00:28
So adp, or what we'd say, adenic phosphate, dye phosphate.
00:44
And then the atp, of course, is then adenosine triphosphate.
00:56
Okay, so emphasis here on the tri.
00:58
So i'm going to draw a really simplified version of these molecules.
01:08
Like i said, very simplified.
01:10
What i'm most concerned with are these phosphates.
01:16
On this adp molecule.
01:17
Okay, so like i said, very, very simplified.
01:21
Adinicine diphosphate has an adenine, a ribose sugar, and then two phosphate groups.
01:27
I'm going to put little peas on the phosphates, just so we know.
01:32
Okay.
01:34
So in order to create an atp molecule, adp must be combined with an inorganic phosphate group.
01:47
So i'll make my atp molecule on this side.
01:59
Okay.
02:00
I'll drop my p's for my phosphates here.
02:04
Okay, so notice the big difference between these two molecules here is the fact that adp just has two of these phosphate groups.
02:11
Atp has a third...
