In order to answer this question, let's talk about metabolism.
00:03
Question was, is in anaerobic organisms, nad plus is reduced in fermentation instead of in glycolysis.
00:09
And this option is false, okay? or this question is false because during glycolysis, you're going to extract with a glucose molecule, and you're going to produce two pyrobin molecules here.
00:22
One pyrobit and another pyrobit.
00:23
And normally here you reduce nad plus and you produce an adhd, okay? but in fermentation, in lactic acid fermentation, for example, pyrobed is going to be converted to lactate or lactic acid, and this nadh is going to be oxidized back to nad plus in order for glycolycolicies to be able to continue because glycolycores requires nad plus, okay? so this option is false.
00:50
Or this question is false.
00:51
Question number two says, the electrons that flow through all of glucose catalysis in the journey in a molecule of nadh or fadh2, and this is false also because basically, the electrons start here.
01:03
So electrons start in glucose, then these electrons are transmitted to glucose 6 -phosphate, then to fructose 6 -phosphate, fructose -1 -6 -soffate, and so on, until like about here they are transferred to the electron carrier that is in a image, okay, here and also here.
01:20
Then question three says, both anaerobic and aerobic organisms produce carbon dioxide as a result of glucose...
