The image below represents the steps of the Krebs cycle. Which of the following processes correctly describes the event at step #4? pyruvate 3C NAD+ NADH + H+ 1 CO2 acetyl CoA 2C 9 oxaloacetate 4C citrate 6C NADH + H+ NAD+ 8 2 malate 4C isocitrate 6C 7 fumarate 4C NAD+ 3 CO2 NADH + H+ FADH2 FAD 6 CO2 a-ketoglutarate 5C succinate 4C P 4 5 NAD+ NADH + H+ GTP succinyl CoA 4C GDP A. A 5-carbon sugar is oxidized to another 5-carbon sugar, which releases a molecule of CO2. B. Electrons released from a sugar are captured by CO2, and coenzyme NAD+ is oxidized. C. Oxidation of a sugar releases a molecule of CO2 as the coenzyme NAD+ captures electrons. D. ATP is synthesized from the phosphorylation of ADP with an inorganic phosphate.

Transcript

00:01 In this question, we are going to talk about the creps cycle.

00:07 This question is going to center about the crep cycle and we have to find what is happening in the fourth step.

00:17 We have to find what is happening in the fourth step.

00:20 So let's move on to the answer.

00:23 So what happens in the fourth step? first, what is cripp cycle? crep cycle is the one which produces the atp.

00:29 So first glycolycolicysis is happening.

00:31 And then it moved on to the link reaction and at last moves to the mitochondria for the crept cycle and what is crept cycle in crept cycle is also called as citric acid cycle because prep cycle starts with the citric acid cycle as in link reaction acetal co -enzyme a is present and this acetyl co -enzyme a will bind with oxaloacetic acid will bind with oxalo acetic acid and this acetyl coentimea and oxaloacic acid move on to the citric cycle which makes the citric acid and that's why this crept cycle is starting with the citric acid cycle and it makes the name of the crep cycle and then it moves to the series of actions and it again moves to the four carbon compound from the six carbon compound which is a 6thic acid cycle and this 4 carbon compound will again move on to the cycle with astell coenzymia and forms a septic acid and it releases 38 atp molecules in the move this molecules will help to produce the energy but in this question we are going to talk about the fourth step that is we are going to talk about what has happened in the transformation of alpha ketogluterate, which is a 5 -carbon compound to sassanile co -enzyme a.

02:09 How this alpha -keterate is changed to succinil -oenzyme a, which is a 4 -carbon compound.

02:19 So here, 5 -carbon compound is reduced to 4 -carbon compound.

02:25 So, a carbon dioxide was released from the alpha -gater -glotrate, a carbon was released.

02:32 Here, carbon was released.

02:34 So this carbon -released formation, this carbon release process is called as decarboxillation...
