Chapter 187 A Casual Electric Eel Voltage-Gated Sodium Channel Experiment

Juventus moved slightly in the direction of Cheng Qing.

"The location of the sodium ion channel is generally on the cell membrane, which can trigger and conduct action potentials, and can then participate in physiological processes such as nerve signal transmission, muscle contraction, etc.."

After hearing these words, Cheng Qing immediately sat up straightened his back.

He looked at the young female educator with horror.

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

He has been confused about the research on sodium ion channels, and there are really few people in China who have studied this area.

Unexpectedly, this female teacher actually said it very well.

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

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

I saw Juventus and Cheng Qing in the judges' seat exchanged enthusiastically.

The people in the live broadcast room were blown up.

[I Yuri Safety]: Why did that woman chat with Cheng Qingcheng so happily?

[Hi pepper is drunk!]: Mr. Cheng is a monument in biology in China. How can ordinary people have topics to talk about? I think this woman has two tricks.

[My brother is a dog]: I really didn’t expect that in such an important occasion, those with backstage can also come on stage to gilt!

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

He is a researcher at 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 attend the judges of the National Middle School Student Knowledge Competition.

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

A top figure in biology research at home and abroad.

He was content when Liu Yang could reach the level of half of Mr. Cheng.

"Tsk! Who is this? He is so happy to chat with my idol!"

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

"Old Cheng is really giving her face."

Liu Yang was watching the video while complaining.

I was very happy to see Juventus and Mr. Cheng chatting.

Cheng Qing looked at him asking for advice, and he felt really unhappy.

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

There are only players from the 72 teams left in the center of the platform.

The second round of the game began soon!

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

"Any theory needs to be supported by experiments. This is an attitude of seeking truth from facts and our attitude towards pursuing the path to truth."

"All the efforts are worth it, and we will enter our second round!"

"The biological neural activity response experiment begins!"

I saw a series of cameras aimed at the students' experimental bench below.

The laboratory bench is filled with various precision instruments and clean white gloves.

Behind the stage were students standing serious and serious!

Slight sweat came slightly on Zhang Tao's face!

His hands trembled slightly when he picked up the white gloves!

"Don't be afraid! Stay calm, Zhang Tao, stay calm!"

"Nothing for anything else, I also want to be proud of Teacher Juventus on the stage!"

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

Teacher Juventus 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 expectant.

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

Juventus's argument also opened a passage,

Something seemed to be open in my mind, but I was a little confused.

He is eager to give Juventus a detailed explanation.

Juventus smiled,

I looked up and looked down at the stage.

Half of the student experiment competition, some students could no longer withstand the pressure.

Some are sweating profusely.

Some of their nervous hands were shaking.

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

Walked off the stage.

"Mr. Cheng is theoretically very feasible, and this still needs experiments to test."

After she finished speaking, she stood up.

Cheng Qing looked at her in confusion.

She quickly walked to a laboratory table.

Wear gloves quickly,

Turning his head and saying a few words to the staff's ear,

The staff quickly ran off the stage and quickly brought a live electric eel.

Cheng Qing suddenly understood what Juventus meant.

He also came to the laboratory bench.

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

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

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

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

"What's going on? This woman said quite professionally!"

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

The camera lens is also aimed at Juventus's laboratory bench.

Given a huge live broadcast screen.

[I love roses]: It turns out that it is my teacher You, I really don’t disappoint me!

【Ona】: What? Is she very powerful?

[Qianpaola]: If you don’t understand, go and read Teacher You’s video.

[Buy it and smile]: You can tell what words are all about? Why don’t you know what it means when you connect it?

"By constantly consuming the Atr to transport sodium and potassium ions, a positive and negative electrochemical gradient can be established inside and outside the cell membrane, that is, the state of preparation for discharge. I will give it a name called resting potential."

"We're opening a sodium ion channel now." Juventus said quickly and opened the precision instrument.

A piece of eel cells had been accurately removed from the lens.

She twisted her magnifying glass and said, adjusting the data.

"After opening the sodium ion channel, sodium ions will enter the cell under the action of a different concentration and produce a series of chain reactions,"

"It can then cause more channels to open, and a large number of sodium ions pour into the cell membrane, so the potential near the membrane will be instantly flipped."

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

Cheng Qing showed a look of surprise on his face.

"This...this...this...this...this, did you invent this?" he asked in a trembling voice.

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

Including the experiment she did on such a simple laboratory bench today,

It actually proves the theory she said,

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