At the moment when Huang Xing finished finishing class, he saw the mockery on Lin Gan's face, and there was a burst of anger in his heart, and he said in a deep voice: "Teacher Lin, don't you have a different opinion on this question?" ”

Lin Qian was quite surprised, this Huang Xing had to drag himself into the water in the end?

Before Lin Qian could react, Huang Xing had already taken a piece of chalk and put it in front of Lin Gan, and said.

"Since Mr. Lin has his own unique views on this question, why don't you give it a try?"

How could Lin Gan not see the meaning of Huang Xing's words, it seemed that he was soliciting opinions, but in fact, he was just waiting to see Lin Gan's jokes.

In terms of biology, Huang Xing, as a doctoral student, has this confidence.

Lin Qian didn't hesitate, took the chalk, and walked towards the podium.

As the homeroom teacher of the sixth class of the third year of high school, students have questions that they can't do, and of course they have the responsibility to explain them well.

"Ding, get recognition point 10."

Before he started to explain, the system had already prompted the recognition points, which made Lin Qian a little crying and laughing.

"Let's take a look at the fourth multiple-choice question, Wang Wenlong, you can read the question."

Wang Wenlong stood up and read aloud.

"After meals, the concentration of glucose in the epithelial cells of the small intestine is higher than that in the blood, and the description of glucose entering the blood from the lumen of the small intestine is correct......"

"A: Endocytosis"

"B: Assisted proliferation"

"C: Active Transport"

"D: exocytosis"

Lin Qian nodded with satisfaction and said, "Please sit down......"

As he spoke, Lin Qian picked up the chalk and drew a simple line on the blackboard, with Na+ written on the top of the line and K+ written on the bottom of the line.

Then he said: "We know that the way a substance enters and exits the cell is different, depending on the situation, and the energy required by animal cells for the absorption of organic substances such as glucose or amino acids is not provided by ATP, so who knows what is provided?" ”

Lin Qian suddenly changed his words and began to ask questions. The student was lost in thought, but soon, someone reacted.

"I know that it is provided by the potential energy in the Na+ electrochemical gradient, which is said in the textbook."

Lin Qian was very satisfied with the student's answer and continued.

"Yes, the operation of the sodium and potassium ion pump forms a Na+ electrochemical gradient to drive the glucose co-transport carrier to enter the small intestinal epithelial cells in the same direction of co-transport, and then enter the blood through the assisted diffusion of GLUT2, so as to complete the absorption of glucose."

When Lin Qian finished explaining, the classroom was silent for a while, and then there was a burst of violent applause.

Lin Gan's explanation was not very exciting, and the topic was not very difficult, but because of the sense of oppression that Huang Xing brought to the students just now, they couldn't understand it at all in Lin Gan's body.

"Teacher Lin is so silky!"

"yes, I understood as soon as I heard it."

"What kind of bullshit Imperial Doctor of Biology, it's not as good as our Teacher Lin!"

Lin Qian smiled with satisfaction, not because of the praise of the students, but because of the recognition point that the system rolled in.

"Ding, get recognition point 10."

"Ding, get recognition point 10."

……

At this moment, Liu Fu came out of the fifth class of the third year of high school, and when he heard the applause and applause of the sixth class of the third year of high school, he couldn't help but feel happy in his heart, and his affirmation of Huang Xing increased a few points.

"Hmph, Lin Qian! Your students have already recognized Huang Xing so much, look at how you will mix in front of them in the future! ”

With a proud mood, Liu Fu came to the door of the sixth class of the third year of high school, but saw a scene that surprised him.

The students of the sixth class of the third year of high school were indeed applauding, but it was not Huang Xing who was standing on the podium, but Lin Qian.

What the hell is going on? This made his brow furrow, and his little eyes narrowed again.

Huang Xing, who was speechless, saw Liu Fu walk in, his eyes lit up, and he hurriedly walked in front of him.

"Director Liu, Mr. Lin gave a lecture to the students privately, and he still gave a wrong answer, isn't this misleading the students? Look at this ......."

Hearing this, not only Liu Fu's face became gloomy, but even the highly respected teacher Zhao beside Liu Fu was not good-looking.

Liu Fu naturally saw the changes in Teacher Zhao's eyes, his eyes had turned, and he had a plan.

"Mr. Zhao, look at this question, what do you want to choose?"

Liu Fu also did not have the slightest doubt about Huang Xing's professional ability, whether the doctor of biology in the Da Yu Empire was not as good as a small undergraduate, it was simply a joke.

The fifth class of the third year of high school has already finished class, and they are all attracted by the scene that happened in the sixth class of the third year of high school, of course, there are not only students who are watching, but also bad teachers and Ye Ling.

Ye Ling glanced at Lin Gan, as if he was really asking what the situation was, Lin Qian made an ok gesture, signaling to reassure him, and Ye Ling was a little relieved.

Teacher Zhao took the test question and looked at it at it, and then laughed.

Liu Fu didn't know what to say, and hurriedly asked, "Teacher Zhao, do you look at this ......question?"

"Well, this question is very good, I wanted to say it just now, this question doesn't seem difficult, but it's actually very confusing."

Saying that, Mr. Zhao had already walked to the podium, looked at the blackboard, erased the exquisite cell diagram drawn by Huang Xing just now, and only left a line drawn by Lin Qian, and then said to the students who were curious about what the answer was.

"We know that in neuromodulation, there are two ways of Na+ and K+ movement, Na+ influx when excited, and K+ influx when stable, which is to assist diffusion."

"But if you want to keep the K+ in the cell, the Na+ outside the cell must be actively transported."

"Let's look at this question again, it is obvious that from the inside of the intestinal lumen to the small intestinal epithelial cells, ATP is originally needed to provide energy, but with the help of ion pumps, potential energy is provided, and from the small intestinal epithelial cells, into the bloodstream, only a carrier is needed, and no energy is needed at all."

When it comes to this, in fact, the answer is already very obvious, the answer is to choose B, but Liu Fu doesn't understand these things, watching the students listen carefully, as the director of the Academic Affairs Office, he is still quite pleased.

"In that case, do the students already understand what to choose for this question?"

Teacher Zhao is a kind little old man, after finishing the question, he wiped the chalk on his hand with a smile, and said to the people below.

The students in the sixth class of the third year of high school said in unison: "Understood." ”

Liu Fu was about to scold Lin Gan, but when he saw Huang Xing, whose face was pale, he secretly screamed in his heart.

"Could it be that what Lin Qian said is right?"
