So let's start with the first question.
00:03
When we talk about acetyl -coa, estal co -a is produced by oxidative coaxillation, but it cannot be taken from the blood.
00:13
And as it cannot be taken from blood, it cannot be transported through blood.
00:17
And when we talk about glucose, glucose basically broke down into the pyruvate, which is a three -carbon molecule by colosis.
00:25
And then this pyruid enter the tca cycle or tricarboxic acid, cytopic acid.
00:30
And it is converted into acetylcoa, the mitochondrial membrane and other biomolecules and proteins also enter the tca cycle.
00:42
So other proteins and different biomolecules also enter the tca cycle.
00:46
So we can see that a cell co -inzyme a is produced during the pathway and it entered the tca pathway for further metabolism and a is formed on the mitochondrial surface.
01:00
Means it basically converted, the pyruid is converted into the cholesterol coenzyme before it enters into the mitochondria and inside the mitochondria and it is not taken up from the blood.
01:09
So option d here for the first question is correct.
01:13
Let's move on to the second one.
01:15
When we talk about acetoacetate, so acetoacetate or we can say a ketone body is taken up from the blood by the cell and this particular cell will have mitochondria and this estroacetate will later be converted into acetyl coa but the question is asking about which is not taken from the blood so we can say that option a here is absolutely incorrect so this is absolutely incorrect let's move on to the next one that is the third one when we talk about lactate lactate can be synthesized or can be produced during the anaerobic respiration process by the lactic acid fermentation and it can it is commonly observed in muscles during the process of exercise when there is low oxygen so we can say this lactate basically is transported from the muscles into the liver cell and it has been recycled back into the glucose and to the braydown so lactate is transported we can say it is transported through the blood and later on been taken by the liver cells from the blood...
