Hi there.
00:02
I'm glad you asked this question.
00:05
So to answer karen's question as to why she needs more cups of coffee in order to feel the same effect that she did earlier with fewer cups, what you would tell her is that karen has developed a caffeine tolerance.
00:19
And to go a bit deeper into that, i'll start by drawing out what the molecular structure of caffeine looks like.
00:26
Just very briefly, it won't be anything too complicated.
00:29
But to put it simply, this might be a bit messy, but i'll do my best.
00:41
I apologize.
01:06
Okay, almost done.
01:08
And voila.
01:12
So i know this isn't the prettiest drawing of a molecule that you've seen, but it gets the job done.
01:17
So this is basically what our dear friend caffeine looks like.
01:26
And how caffeine works is that it acts as a competitive inhibitor to another molecule in your body called adenocene.
01:34
And so what adenosine is responsible for is it's what makes you feel drowsy and tired at the longer the day it goes on.
01:43
And so what happens is over here and another colored.
01:48
I've drawn, i'm going to draw a very basic representation of what is an adenosine or deceptor.
01:55
Basically, this is the stuff that latches on to adenosine, which i will draw in green here.
02:04
So normally this guy would go in here, lock on, and work as a deco scene.
02:07
It's magic, and the end result would be that you'd feel tired and drowsy throughout the day...
