Juventus moved slightly in the direction of Cheng Qing.

"Sodium ion channels are generally located on the cell membrane, so they can initiate and conduct action potentials, which can then participate in physiological processes such as nerve signaling and muscle contraction."

After hearing these words, Cheng Qing immediately sat up straight,

He looked at the young female educator with a shocked expression,

I really didn't expect that this beautiful, dignified girl would have such profound attainments in the field of biology.

He has been puzzled by the study of sodium ion channels, and there are really few people who have studied this area in China.

I didn't expect this female teacher to say the Tao.

Juventus did not pause because of Cheng Qing's expression, and continued:

"The sodium channel in the cell senses the change of membrane potential activation or inactivation, and in the resting state, the potential in the cell is low, and the potential difference between the two volumes of the cell membrane with a thickness of 3-5 nanometers is about 70 volts."

I saw the enthusiastic exchange between Ju Wenwen and Cheng Qing on the judges' bench.

The people in the live broadcast room blew up.

[I'm Yuri safe]: That woman, why is she so happy chatting with Cheng Qingcheng?

[Chili is drunk! ] ]: Cheng Lao, that's a biological monument in China, how can ordinary people have a topic to talk about? I think this woman has two brushes.

[My brother is a dog]: I really didn't expect that on such an important occasion, these backstage people can also come on stage to gild!

Liu Yang washed his hair and swiped his mobile phone while eating.

He is a researcher at a pharmaceutical company and has just finished working on a project.

The next two days of rest will bring him a lot of energy.

He had long heard that Cheng Qing would be a judge of the National Middle School Knowledge Competition.

Cheng Qing, that's the star he has been chasing!

A top figure in biological research at home and abroad.

When will he, Liu Yang, be content with half of Cheng Lao's level.

"Cut! Who is this, you actually have such a happy chat with my idol! ”

"That is, if you have a mine at home, you can do it in that position!"

"Cheng Lao really gave her face."

Liu Yang complained while watching the video.

Watching Ju Wenwen and Cheng Lao chatting very happily,

Cheng Qing looked like he was asking for advice again, and he was really unhappy in his heart.

On the stage, the 288 teams participating in the national competition have screened out more than half of the contestants after the first round of answering questions.

In the center of the stage, only the players of the seventy-two teams remained.

The second round of the competition started soon!

"Thank you to the elite teams across the country for participating in our knowledge competition!" The boy who is thick with Xiao Sa sounds!

"Any theory needs to be supported by experiments, which is the attitude of seeking truth from facts, and it is also the attitude of our pursuit of truth."

"All the hard work is worth it, let's move on to our second round!"

"Biological Neural Activity Response Experiment Begins!"

I saw a camera pointed at the student's laboratory table below.

The lab bench is filled with a variety of sophisticated instruments and clean white gloves.

Behind the platform stood students with serious and serious expressions!

There were slight beads of sweat on Zhang Tao's face!

His hand as he picked up the white glove trembled slightly!

"Don't be afraid! Steady, Zhang Tao, steady! ”

"Not for anything else, but also for the Juventus teacher on the stage!"

He secretly made up his mind, and couldn't help but raise his head and look at the jury.

Teacher Yu Wenwen is still chatting with Cheng Qing.

He also slowly calmed down.

"Xiao You, what is the near-atomic resolution structure of the eukaryotic voltage-gated sodium ion channel you are talking about?"

Cheng Qing looked forward to it.

He had never heard of eukaryotic voltage-gated sodium ion channels,

Juventus's arguments opened a channel for him to too,

Something seemed to open up in my mind, but I couldn't figure it out.

He was desperate for Juventus to give a detailed explanation.

Juventus smiled,

He raised his eyes and looked under the lookout.

More than half of the student experiment competition, some students can no longer withstand the pressure,

Some sweat profusely,

Some nervous hands trembled.

There are even a few who even gave up the game directly,

Walked off the stage.

"Cheng Lao, theoretically it is very feasible, and this still needs to be tested by experiments."

With that, she stood up.

Cheng Qing looked at her suspiciously.

I saw her quickly walk to a laboratory table,

Swift with gloves,

Turning his head into the ear of the staff, he said a few words,

The staff quickly ran to the stage and soon brought a fresh electric eel.

Cheng Qing immediately understood what Ju Wen meant,

He also came to the test table.

"Cheng Lao, you see, almost all animals have a transmembrane protein on their normal cells, which is the sodium-potassium pump."

"Its only function is to consume 1 ATR and transport 3 sodium ions out of the cell, and at the same time transfer 2 potassium ions into the cell, which is equivalent to pumping out a positive charge."

Cheng Qing kept nodding, and his eyes showed joy and joy.

Liu Yang, who was swiping his mobile phone, couldn't help frowning when he heard this.

"What's the matter, this woman's words are quite professional!"

"Is it really not a vase, but a real scientist?"

The camera's lens is also aimed at Juventus's test bench,

Gave an extra-large live broadcast screen.

[I Love Roses]: Sure enough, it's still my Teacher You, who really doesn't disappoint me!

Ona: What? Is she amazing?

[Money is coming]: Upstairs if you don't understand, go to look through Mr. You's video.

[Buy a smile]: You can know what words you say? Why don't you know what it means when you connect them?

"And by continuously consuming ATR to transport sodium and potassium ions, we can establish a positive and negative electrochemical gradient inside and outside the cell membrane, that is, the state of preparing for discharge, which I call resting potential."

"We're now opening a sodium channel." Juventus said while opening the precision instrument with his hands and feet,

A piece of eel cell has been accurately removed from the lens.

She twisted her magnifying glass and adjusted the data as she spoke.

"When the sodium ion channel is opened, the sodium ions enter the cell under the action of the concentration difference, and a series of chain reactions are generated,"

"This in turn causes more channels to open, and a large amount of sodium ions rushes into the cell membrane, so that the potential near the membrane is instantly reversed."

"At this time, it becomes positive inside and negative outside, which is actually a discharge."

Cheng Qing's face showed a look of surprise.

"This... This.... Mr. You, did you invent this? He asked, in a trembling voice.

You know, Juventus today talks about the theory of electric eel voltage-gated sodium ion channels,

Including the experiments she did today on such a simple test bench,

actually proved the theory she said,

This is simply a subversive theory and guidance for the medical community and the biological community.

All this will bring great shock to China and the world, and will surely lead medicine and biology to a higher level.
