Hello students in this question we have to select the correct answer for the pathway which produces carbon dioxide as a waste products.
00:09
So here let's start the correct answer is option c and option e which is option c is alcohol fermentation and option e it is citric acid cycle as the citric acid cycle this is also known as a citric acid cycle this is also known as as the krebs cycle and this is a part of cellular respiration and take place in mitochondria.
01:12
And it starts with the acetio coenzyme a produced by the pyruate dehydrogenase enzyme and co2, this is produced during the several de -carboxylation reaction of the krebs cycle or citric acid cycle.
01:54
And the reaction, they are catalyzed by the enzymes which are alpha ketoglutrate, dehydrogenase.
02:17
And co2, this is also released by the alcohol fermentation.
02:30
During the alcohol fermentation, the sugar -like glucose, they are converted to ethanol with the release of carbon dioxide.
02:46
So we can say option a, c and e, these are correct.
02:49
Now let's see other options like option number a which is the lactic acid fermentation.
03:08
So during the lactic acid fermentation the 3 carbon pyruid is converted into 3 carbon containing lactic acid.
03:31
So there is no loss of carbon here...
