Okay, i want to answer this question.
00:01
Let's talk about the process of fermentation.
00:03
Remember that everything is going to start with a glucose molecule.
00:07
This glucose molecule is going to be broken down by the process of glycolysis, and two pyruvate molecules are going to be produced.
00:17
One pyruvate here and another pyruid here, okay? during aerobic conditions, it means when oxygen is present, each of these pyruvate molecules are going to enter, it's going to enter the mitochondrial, and they are going to be converted to acetal co -a.
00:35
And then each acetal co -a is going to enter the crept cycle.
00:39
There are going to be production of nadh, fdh2, and they are going to go to the electric transport chain in order to produce atp.
00:47
But when there is absence of oxygen, everything inside mitochondrial is going to be blocked.
00:53
So pyrobat, in order to, like, in order to produce some energy because most of the energy is producing the electrical transfer chain of mitochondrone, this pyruid is going to shut to the fermentation pathway.
01:05
There are many types of fermentation, okay, but in this case, let's suppose it is like alcohol or ethanol fermentation.
01:12
So this pyruid is going to convert into ethanol.
01:15
Okay, and this is advantageous because remember that during glycolysis, you're reducing an nad plus molecule in order to produce nadh.
01:26
But normally this nadh is oxidized back to nad plus in the electron transport chain of mitochondrial.
01:35
But as it is blocked because of the absence of oxygen, then this reaction here is going to be useful in order to recycle this nadh back to nad plus.
01:44
And nad plus is required for glycolysis to cure...
