For now, just remember that cellular respiration breaks down nutrient molecules to generate ATP.

现在，只要记住细胞呼吸分解营养分子生成三磷酸腺苷。

This process of using oxygen to break down sugars into chemical energy is called cellular respiration.

线粒体利用氧气把糖分分解成化学能的做细胞呼吸。

And we can't forget mitochondria, the kidney-bean-shaped sites of cellular respiration in both plant and animal cells.

我们也不能忘记线粒体，这是植物和动物细胞肾豆状的细胞呼吸部位。

Cellular respiration is the process by which chemical energy stored in sugars is converted to energy molecules that fuel life's essential processes.

细胞呼吸是将储存在糖的化学能转化为为生命的基本提供燃料的能量分子的。

The first bit of glucose gets delivered throughout the body and is tapped to generate ATP on the spot, through cellular respiration.

第一部分葡萄糖被输送到全身，并通细胞呼吸生三磷酸腺苷。

Next time, we'll be seeing these plants in action as they accomplish some of their most important processes: cellular respiration and photosynthesis.

下节课，我们将看到这些植物完成一些最重要的：细胞呼吸和光合作用。

As we've just discussed, cellular respiration is how cells get energy from food.

正如我们刚刚讨论的，细胞呼吸是细胞如何从食物获取能量的。

This is going to be cellular respiration.

这就是细胞呼吸。

And most of the heterotrophs use cellular respiration.

大多数异养生物都采用细胞呼吸作用。

The whole point of cellular respiration is to generate these molecules.

细胞呼吸的整个目的就是生成这些分子。

Because it uses oxygen, cellular respiration is also called aerobic respiration.

因为细胞呼吸使用氧气，所以它也被称为有氧呼吸。

A process called cellular respiration consumes glucose and oxygen to form ATP, the energy currency of the cell.

一个名为细胞呼吸的会消耗葡萄糖和氧气， 以生成ATP，即细胞的能量通货。

Meanwhile other carbohydrates, the ones that are used to produce energy, go through a process called cellular respiration.

与此同时，其他碳水化合物， 即用于生能量的碳水化合物，会经历一个称为细胞呼吸的。

And we'll talk more about that in cellular respiration.

我们会在细胞呼吸部分更详细地讨论这一点。

In other words, oxygen is needed for cellular respiration and carbon dioxide is produced as a result.

换言之，细胞呼吸需要氧气，因此生二氧化碳。

Next let's go to cellular respiration.

接下来，我们将探讨细胞呼吸作用。

Cellular respiration we're actually using the energy in those sugars.

细胞呼吸实际上是利用了这些糖的能量。

Most of us may think of Vitamin C as Citric acid, which is generated during cellular respiration of mammals including humans, but actually, it is not.

我们大多数人可能认为维生素 C 是柠檬酸，它是包括人类在内的哺乳动物细胞呼吸生的，但实际上并非如此。

Now, the conversion of food energy is part of the great balancing act that is maintaining homeostasis, and one of its greatest tricks is cellular respiration.

食物能量的转换是维持体内平衡的伟大平衡行为的一部分，它最伟大的技巧之一是细胞呼吸。

It's only by working together and using both the bulk flow and simple diffusion of oxygen that they can make possible the process of cellular respiration.

只有通协同工作，同时利用容积运动和氧气的简单扩散，它们才能使细胞呼吸的成为可能。
