Adenosine is found all over your body.

苷酸存在于你身体各个角落。

Those molecules can then be processed and used in the making of ATP.

这些分子可以被加工并用于制造三磷酸苷。

Firstly, caffeine blocks the receptors in the body for a compound called adenosine.

首先，咖啡因会阻断体内对苷化合物受体。

In other words, it makes you feel relaxed.

换句话说，苷能让你感到放松。

There are four bases: adenosine, thymine, cytosin, and guanine.

苷、胸嘧啶、胞嘧啶和鸟嘌呤。

Caffeine gets in there and blocks that receptor so you never feel that tiredness.

咖啡因到脑区 阻碍苷与受体结合，所以你不会感到疲惫。

In fact, caffeine works by blocking adenosine's receptor pathways.

事实上，咖啡因是靠阻断接受苷感知器官来实现其作用。

You get way more ATP for every bit of organic matter that you consume.

你摄入每一点有机物都会让你获得更多三磷酸苷。

It's about 10 times more efficient than those original anaerobic ways of creating ATP.

这比原来用厌氧法产生三磷酸苷要高 10 倍。

No, no, no, it only stops your heart for six seconds...-Meredith, it's adenosine.

不，不，不，这个只会停住你心跳6秒... -Meredith，是苷。

Caffeine is a pro at mimicking a neurotransmitter called adenosine.

咖啡因是一种能够像“苷”神经递质一样在神经细胞间传递信息。

But it turns out that the caffeine in your coffee is incredibly similar to adenosine in structure.

而咖啡中咖啡因与苷化学结构非常相似。

An organelle whose main job is to create ATP for its host cell.

一种细胞器，其主要工作是为宿主细胞产生三磷酸苷。

A whole new way of making ATP, and lots of it.

一种制造三磷酸苷全新方法，还有很多其它把戏。

As adenosine builds up, it increases the urge to sleep, also known as sleep pressure.

当苷累积起来时候，它增加了困倦感，也就是睡眠压力。

The substance concerned, TDI-11861, belongs to a class of molecules called soluble adenylyl cyclase (sAC) inhibitors.

这种名为TDI-11861物质属于可溶性苷酸环化酶(sAC)抑制剂。

As your body loses the capability of creating ATP, and you start to physically fall apart.

当你身体失去制造三磷酸苷能力时，你身体就开始崩溃。

Remember, ATP is kind of like molecular currency.

记住，三磷酸苷有点像分子货币。

Hypoxia prevents their mitochondria from producing Adenosine Triphosphate or ATP, which is the cell's main source of energy.

缺氧使线粒体产生三磷酸苷（ATP）过程受阻，而ATP正是细胞主要能量来源。

So caffeine stops adenosine from doing its thing, while some stimulating neurotransmitters are still around.

所以说咖啡因抑制了苷酸执行它职责，而那些兴奋神经传导物质依在周围。
