00:01
Okay, i'm going to answer this question.
00:01
Let's talk about metabolism.
00:03
Question number one says, which enzyme subunit cofactored in alpha -kidohydide dehydrogenase is mismatched? remember that the enzyme alpha -kidoglutergutase catalyzes the reaction from alpha -kloatate.
00:16
Okay.
00:19
From alpha -kidoblutate to succinyl co -a.
00:23
Okay, to succinctal co -a.
00:25
We're going to use many co -factors here.
00:28
And remember that this alpha -kiroluterate dehydrogenase is going to be a lot of like a sound to have a same sunycinics as a transpirovetic hydrogenase complex, okay? you're going to have e1, e2, and e3, and you're going to have many cofactors that are going to act here.
00:43
For example, in e1, you're going to have the cofactors that is thiamine.
00:51
In e2, you're going to have oa, and in e3 you're going to have a hypoic acid.
01:00
In hearing, e3, you're going to have an adh and faddh.
01:06
Or practically nad and fovd.
01:10
It is going to be a co -factor.
01:11
So let's look at the options.
01:13
Option a says e1 and coae, and this is false, and this is the answer for this question, because coa is a co -factor for a, so for e2, for the second subjunit.
01:24
Now let's go for question number two.
01:28
That says, how many atp equivalents are in single molecule of acetyl coa? acetal co -a, remember that there is a molecule that is going to enter, it is going to react with oxaloacylacety, and it is going to enter the crept cycle.
01:38
Produce in citrate.
01:39
Then many metabolites are going to be produced but in general what you're going to produce here are three molecules of nadh, one molecule of fadh 2, and one molecule of atp.
01:52
Remember that in the electron transport chain is this nadh are going to code 4 2 .580ps and each fadh 2 is going to produce 1 .580p so you have to replace this here and you're going to have here 2 .5 multiply by 3 and this is it's going to be 7 .580ps.
02:11
Here you're going to have 1 .580ps.
02:14
And here you have 180.
02:15
So you just add all of this and you're going to get 1080ps.
02:19
So the answer for this question is going to be option b that is 10.
02:22
Now let's go for question number three that says, saxonyl dehydrogenase is an enzyme complex shared with, remember that saxonylid dehydrogenase is an enzyme that is part of the curve cycle.
02:34
Okay, but also it is the complex number two of the electric transport.
02:38
So this enzyme is practically shared in those two reactions.
02:46
And the answer for this question, number three is going to be option b, because i see an idea dependent on it is like about here.
02:55
And it is also part of the electro -transport chain, as i said, and the electric transport chain is found in the inner mitochondrial membrane.
03:02
Okay? now we have question four that says, which enzyme mechanism involves both the additional and the subtraction of water...
