Chapter 165 Who else!
Zhao Yueer blushed, "The function of the competitive inhibitor is to make the enzyme mistakenly believe that it is a substrate, so as to preemptively bind to the enzyme and inactivate the enzyme."

"If it is a competitive stepmother, then the measures she should take are: dress up as Cinderella herself, and then go to the prince's bed, so that the prince will not be able to go to Cinderella if he has a stepmother."

After finishing this passage, Zhao Yue'er looked at Yang Tian with twinkling eyes. Before Yang Tian had time to say anything, there was a sudden "Puff!"

One of the two first-year men who forced Zhao Yueer to question just now opened his mouth wide, and water mist sprayed out from his mouth slightly to the right, and then hit the other first-year man head-on and face-to-face!

"Fuck!"

The buddy who was attacked screamed and turned backwards in an instant, and then there was a tooth-piercing sound of the chair moving.

Yang Tian's eyes were sharp and he pulled his hand quickly, and Zhao Yue'er narrowly avoided the overturned chair with a gap of 5 centimeters.

The senior boy sitting next to Zhao Yue'er was not so lucky, he was bumped into his chest by the buddy who was evading the attack, and the sound of "hey" was obviously painful.

The table was slightly wet, and the buddy with the kettle in his hand looked back at Zhao Yue'er and Yang Tian in a daze, and made 666 with the other hand.

"Amazing my brother and my sister!"

"Amazing your size! If you don't drink water early and late, you are amazing!"

The buddy who was sprayed with half of his face turned around and gave him a chestnut fried in sugar, and then turned his head to look at Yang Tian and Zhao Yueer, "I kneel down for you, I will give you 82 points for this lesson, and the rest The 18 points of the score will be compared to you in the form of 666!"

Zhao Yue'er's face was already ashamed, but Yang Tian was quite calm, after all, he was the one who showed off in front of nearly a hundred people, so what's wrong with that!

Smiling, Yang Tian looked at Zhao Yue'er and began to smooth things over, "Actually, it doesn't need to be so dirty."

Zhao Yue'er's face, which had just regained some whiteness, turned red again when she heard the words, and then she heard Yang Tian say:

"The stepmother is quite old, so we don't have to fight like this, we can let her send her own daughter to the prince's bed, right?"

Everyone was silent for a while, and then complained in their hearts, isn't this the same dirty thing!

"Why do you all have such expressions?" Yang Tian looked serious, "We are discussing science, where are you all thinking! Really, you must study hard and be the successor of socialism!"

Everyone remained silent, the expressions on their faces twitched, Zhao Yue'er looked at Yang Tian's serious nonsense, and the corner of his mouth couldn't help but twitched into a smile.

"Okay, stop talking, let's go back to the question just now."

Yang Tian cleared his throat, "How will our Km and Vmax values ​​change after the competing stepmother kidnaps the prince?"

"I know this." Zhao Yueer volunteered, reminding herself that this is a discussion of science, while saying:
"When the stepmother and Cinderella can marry the prince, the prince is not Cinderella, so the intimacy between the prince and Cinderella will decrease, that is to say, the affinity between the enzyme and the substrate will decrease. We know that The smaller the Km value, the higher the affinity, so the Km will become larger at this time."

"Yes, what about Vmax?"

Yang Tian followed the temptation, and the students around couldn't help getting closer. The water bottle of the man who sprayed water just now has been confiscated by everyone. Without any threat, everyone still wants to hear Yang Tian use this method to popularize science. Are you happy?

"I also know this!" Zhao Yueer continued to answer, "Because there are still so many princes, but if they all choose Cinderella instead of stepmother, the speed at which Cinderella becomes princess is still the same, so Vmax will not change."

Everyone nodded one after another, that's the reason.

"Very well, then let's talk about another kind of stepmother, non-competitive stepmother, do you know the mechanism of action of this kind of stepmother?"

Yang Tian asked the next question with a smile, Zhao Yueer opened his mouth, then shook his head dejectedly and shrank back.

She told Yang Tian before that she could probably guess the principle of the change of the two parameters caused by the non-competitive inhibitor, but in fact she was still dizzy, and she didn't particularly understand the reason behind it, let alone to She said it with simple examples.

Yang Tian glanced back, "Is there anything you want to try to answer?"

Everyone hesitated for a while, then shook their heads.

The two freshmen didn't learn this lesson at all, because Zhao Yue'er was actually just previewing.

The seniors in the senior grades thought about it carefully. What they learned in the course of biochemistry at the time was really painful for them. There were a lot of formulas and steps to memorize, and now their subjects made them feel even worse. Egg hurts, so although I vaguely remember that there are so many inhibitors, but the principle of action has been almost forgotten.

The buddy who broadcast live in the qq group also threw the whole process and this question into it, and the qq group exploded in an instant, "666" and "999" flew all over the screen, but no one knew it.

The two senior sisters were eager to try. After all, girls are more serious about studying than boys, so they remember more or less, but when they thought of Zhao Yueer's embarrassment just now, they shrank back one after another.

So in the end it was Yang Tian himself who smiled and went on top.

"Non-competitive inhibitors can bind to places other than the active center of the enzyme, and will not affect the binding of the enzyme to the substrate, and the substrate will not affect the binding of the enzyme to the inhibitor. There is no competitive relationship between the substrate and the inhibitor, but The inhibitor-enzyme-substrate complex cannot release the product."

"Probably means that the non-competitive stepmother will not compete with Cinderella for the prince, she will only follow him by the hem of the prince's clothes, which will not affect the prince's relationship with Cinderella, and at the same time the prince and Cinderella's relationship Even Cinderella couldn't stop the stepmother from quietly grabbing the prince's clothes from behind."

"So strictly speaking, neither stepmother nor Cinderella affects anyone, so there is no competition."

"Then the question is, how does this stepmother inhibit the enzymatic reaction?"

Everyone's eyes were focused on Yang Tian, ​​and the buddies who were broadcasting live in the group didn't care about their cell phones that kept ringing, and stared straight at Yang Tian.

Yang Tian cleared his throat and continued.

"Although the stepmother can't prevent the prince and Cinderella from going online, but because she has been holding the prince's clothes, even if the prince and Cinderella have a wedding, they can't live in the bridal chamber under the supervision of the stepmother. Cinderella therefore It is impossible to become a princess, and the enzymatic reaction cannot proceed smoothly."

Everyone opened their mouths and widened their eyes. They never expected that Yang Tian could give such an explanation!

Then they reacted and began to applaud spontaneously. Although Yang Tian's explanation made people unable to look directly at it, it was undeniable that what he said was indeed right!
The combination of non-competitive inhibitors and enzymes will not affect the combination of substrates and enzymes, so the stepmother will not prevent them from holding the wedding by pulling the hem of the prince's clothes.

But when there is a non-competitive inhibitor, the substrate really cannot be converted into a product by the enzyme. If this is placed on the prince and Cinderella, isn't it that they can't have sex in front of the stepmother!

After all, Cinderella and the prince also want face, this is going to be a real bridal chamber, isn't it just a live erotic palace in front of the stepmother!

This explanation is simple!

Who else but Yang Tian!
