Post-00 teacher: students are late, so am I

You Wenwen moved slightly towards Cheng Qing's direction.

"The sodium ion channel is generally located on the cell membrane, so that it can initiate and conduct action potentials, and then participate in physiological processes such as nerve signal transmission and muscle contraction."

Cheng Qing sat up straight after hearing these words,
He looked at the young female educator with a look of horror,
It is really unexpected that this beautiful and dignified girl has such profound attainments in the field of biology.

He has always been puzzled by the research on sodium ion channels, and there are really very few people in China who have done research on this area.

I didn't expect this female teacher to speak clearly and logically.

You Wenwen didn't pause because of Cheng Qing's expression, and continued:

"The sodium channel in the cell is activated or inactivated by the change of the membrane potential. 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 millivolts."

I saw You Wenwen and Cheng Qing in the judging panel exchanging enthusiastically.

The people in the live broadcast room were blown up.

[My Yuri is safe]: That woman, why are you chatting so happily with Cheng Qingcheng?
[Chili is drunk! ]: Mr. Cheng is a biological monument in China. How can ordinary people have something to talk about?I see this woman has two brushes.

[My brother is a dog]: I never thought that on such an important occasion, those who have backstage can also go on stage to be gilded!
Liu Yang washed his hair too much and swiped his phone while eating.

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

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

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

Cheng Qing, that's the star he's been chasing!
Top figures in biological research at home and abroad.

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

"Cut! Who the hell is talking so happily with my idol!"

"It means that there is a mine at home, so you can work in that position!"

"Mr. Cheng is really giving her face too much."

Liu Yang complained while watching the video.

Seeing You Wenwen chatting with Cheng Lao very happily,
Cheng Qing looked like asking for advice again, feeling really upset.

On the stage, more than half of the 288 participating teams across the country have been screened out after the first round of answering questions.

In the middle of the stage, only the players from the 72 teams were left.

The second round of competition will start soon!

"Thank you to all the elite teams across the country for participating in our knowledge contest!" Xiao Sa's honest boy rang!

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

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

"The biological neural activity response experiment begins!"

I saw one camera after another aimed at the students' experimental tables below.

The laboratory bench is full of various sophisticated instruments and clean white gloves.

Behind the stage stood serious and earnest students!
Slight beads of sweat appeared on Zhang Tao's face!
His hand that picked up the white glove trembled slightly!

"Don't be afraid! Hold on, Zhang Tao, hold on!"

"Not for anything else, but also for Teacher You Wenwen on the stage!"

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

Teacher You Wenwen was still chatting with Cheng Qing.

He also slowly sank 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 expectant.

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

Juventus's argument made him also open a channel,

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

He is eagerly looking forward to a detailed explanation from Juventus.

Juventus smiled,
He raised his eyes and looked down the platform.

Halfway through the student experiment competition, some students could no longer withstand the pressure.

Some are sweating profusely,

Some nervous hands trembled.

Several even gave up the game directly,

Stepped off the stage.

"Cheng Lao, theoretically speaking, it is very feasible, but this still needs to be verified by experiments."

After she finished speaking, she stood up.

Cheng Qing looked at her suspiciously.

I saw her walking quickly to a laboratory table,
Quickly put on your gloves,
He turned his head and said a few words into the ear of the staff,

The staff quickly ran to the audience, and soon served a fresh electric eel.

Cheng Qing immediately understood what You Wenwen meant,
He also came to the test bench.

"Cheng Lao, look, there is a transmembrane protein on the normal cells of almost all animals, which is the sodium potassium pump."

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

Cheng Qing kept nodding, with joy and joy in his eyes.

Liu Yang, who was swiping his phone, frowned when he heard this.

"What's going on, what this woman said is quite professional!"

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

The lens of the camera is also aimed at Juventus' test bench,
A huge live broadcast was given.

[I love roses]: Sure enough, it is still my Teacher You, who really does not let me down!

[Onaja]: What?Is she great?

[Qian Pailai]: If you don't understand upstairs, go and look up Teacher You's video.

[Bought a smile]: Can you know the words you say?Why don't you know what it means?
"And by continuously consuming ATR to transport sodium and potassium ions, a positive and negative electrochemical gradient can be established inside and outside the cell membrane, which is the state of preparing to discharge. I named it the resting potential."

"Let's open a sodium ion channel now." You Wenwen said as he opened the delicate instrument deftly.
A slice of eel cells has been precisely removed from the lens,

She twisted the magnifying glass, adjusting the data as she spoke.

"After the sodium ion channel is opened, sodium ions will enter the cell under the action of the concentration difference, and a series of chain reactions will occur,"

"This in turn can cause more channels to open, and a large amount of sodium ions flood into the cell membrane, so the potential near the membrane flips instantaneously."

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

Cheng Qing had a shocked expression on his face.

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

You know, the theory of the electric eel voltage-gated sodium ion channel that Ewing said today,
Including the experiments she did on such a crude laboratory bench today,

It actually proved her theory,

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

How much shock will all this bring to Huaguo and the world, and it will surely lead medicine and biology to a higher level.
