The medical black technology system of the top student

Chapter 38 Top academics all finish their studies in advance



If Lu Liang said he didn't know how to do it at this time, Zhou Feng would not make any criticism. His original intention was to teach students and let them realize their mistakes, not to make students feel disgusted with this course.

But now that Lu Liang said he understood it, the situation was completely different.

In this case, there are two possibilities.

One possibility is that Lu Liangzhen knows it, and he has previewed this knowledge in advance.

But this possibility is almost zero. Can a student who sleeps in class still be expected to study before class?

That leaves only one other possibility.

Lu Liang wanted to pretend to understand what he didn't understand and get through under his nose.

Zhou Feng has always been disgusted with students who pretend to understand. In his opinion, such students are very dishonest and only want to be clever. With this kind of thinking, no matter whether they are academically or socially in the future, they will fail. Can't go far.

At this moment, whispers were also heard in the classroom, and all kinds of gloating eyes fell on Lu Liang. Everyone had the mentality of just watching the fun and not taking it too seriously.

Even Liu Qi couldn't help but frown slightly: What on earth are you doing, Lao Lu? Can't you just say you don't understand? Why do you pretend to understand if you don't understand? Isn't this looking for trouble?

But Cheng Ming on the side replied calmly: Not necessarily, maybe Lao Lu really understands.

Liu Qi was puzzled: But, wasn't Lao Lu sleeping in class just now? He didn't pay attention to the class, how could he understand?

Cheng Ming glanced at Liu Qi: Do you still use ordinary people to measure Lao Lu?

When Liu Qi heard this, he immediately felt that what Cheng Ming said made sense.

During the discussion between Liu Qi and Cheng Ming, Zhou Feng put down the thermos cup in his hand and said with a calm expression on his face: Have you really clarified the knowledge points?

This was the last chance he gave Lu Liang, and now Lu Liang still had room to regret it.

I figured it out. Lu Liang still answered affirmatively.

You've got a hammer!

You fell asleep in class and didn't even listen to the lesson. If you could figure out these knowledge points like this, I would eat the blackboard on the spot!

But after Lu Liangdu said this, Zhou Feng was not polite. He said calmly: Okay, classmate, now you can elaborate on the functions of these two signaling pathways.

Under the gaze of everyone, Lu Liang spoke without hesitation: PPARγ and AMPK signaling pathways both regulate lipid metabolism.

PPARγ can promote fat differentiation and increase the number of fat cells, and the AMPK signaling pathway can inhibit the formation of fat cells and promote lipolysis.

This means that these two signaling pathways have completely opposite effects in the regulation of lipid metabolism.

When he said this, Lu Liang paused.

He knew these two signaling pathways not because he had done some pre-class preparation, but because in addition to regulating lipid metabolism, these two signaling pathways also regulate insulin resistance.

I have to say that life is a very magical thing.

Obviously there are two completely opposite signaling pathways in lipid metabolism, but they play a decisive role in alleviating the body's insulin resistance.

However, Lu Liang's slight pause made Ruan Shishi frown on the side.

Wouldn't Lu Liang's answer be the end of it?

You know, the answer to these two points doesn't mean anything, because she also knows these two points, and the focus is on the downstream of these two signaling pathways.

As expected, Zhou Feng also spoke at this moment: Is that just these two points, classmate, it's not detailed enough.

Lu Liang continued: PPARγ promotes the uptake of fatty acids by cells and accelerates the conversion of fatty acids into acyl-CoA by regulating fatty acid transport protein-1 (FATP-1).

AMPK regulates lipid metabolism mainly by regulating sterol regulatory element binding protein-1c (SREBP-1c) and acetyl-CoA carboxylase (ACC).

SREBP-1c is a key transcription factor that regulates fatty acid synthase. AMPK reduces the activity of fatty acid synthase by inhibiting the activity of SREBP-1c, thereby achieving the purpose of reducing fat synthesis.

On the other hand, ACC, as a long-chain fatty acid rate-limiting enzyme, can promote the conversion of acetyl-CoA to 'malonyl-CoA', the precursor of fatty acid synthesis, and also inhibit the rate-limiting enzyme carnitine ester of fatty acid β-oxidation. Cytyltransferase 1 (CPT-1) activity.

AMPK inhibits the conversion of malonyl-CoA and reduces fat synthesis by phosphorylating ACC. At the same time, it indirectly increases the activity of CPT-1, accelerates fatty acid β-oxidation, and promotes fat decomposition.

After finishing speaking, Lu Liang looked at Zhou Feng: Teacher, I must have said it right, right?

As Lu Liang finished speaking, the entire classroom was silent for a moment.

At this moment, all the students in the classroom who were enjoying themselves with a schadenfreude attitude looked at each other.

Are you serious?

They all thought that Lu Liang was deliberately holding on because he didn't want to be deducted points, trying to pretend to understand.

But I never expected that Lu Liang would actually answer.

For a moment, there were small whispers in the classroom.

Brother, is his answer correct?

How do I know? I only have a partial understanding of the content of this class, and I haven't sorted it out yet.

Aren't you in the top five in grade? Don't you even understand?

Theoretically speaking, he should be talking nonsense. I don't think anyone can figure it out in such a short period of time.

Quiet, everyone, be quiet.

The discussion was quickly stopped by Zhou Feng on the podium. Zhou Feng glanced at Lu Liang: Very good, I understand it well.

Zhou Feng was also deeply surprised that Lu Liang could answer this matter.

He originally thought that Lu Liang was just pretending to understand, but now it seems that he wrongly blamed Lu Liang.

If nothing else, Lu Liang should have previewed in advance or learned about this knowledge somewhere.

This also made Zhou Feng a little puzzled. Logically speaking, students like Lu Liang who take the initiative to learn would not make the mistake of sleeping in class.

Could it be that there are other things that have delayed sleep?

After much deliberation, Zhou Feng could only find this explanation. As for what caused the delay, Zhou Feng did not delve into it. After all, he was a teacher, not a perverted voyeur.

Zhou Feng didn't want to interfere too much in the students' private affairs.

As Zhou Feng's words came out, there was an uproar in the classroom.

Zhou Feng's words clearly acknowledged that Lu Liang's answers were all correct, which made those who originally doubted Lu Liang speechless for a moment.

Didn't you say he was talking nonsense?

Theoretically speaking, he might have been lucky, so he happened to get the answer right. That should be the case.

No, how can this be explained by luck?

But the question is, isn't he sleeping in class? Why can he still answer?

Are you a god? You can listen to lectures in your dreams?

He just glanced at the book and understood everything?
