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

粒体利用氧气把糖分分解成化学能的过程叫做细胞呼吸。

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

我们也不能忘记粒体，这植物和动物细胞中肾豆状的细胞呼吸部位。

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

在，只要记住细胞呼吸分解营养分子生成三磷酸腺苷。

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，并通过细胞呼吸当场产生三磷酸腺苷。

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

细胞呼吸将储存在糖中的化学能转化为为生命的基本过程提供燃料的能量分子的过程。

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，我们将看到这些植物完成一些最重要的过程：细胞呼吸和光合作用。

This is going to be cellular respiration.

这就细胞呼吸。

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。

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

细胞呼吸的整个目的就生成这些分子。

What Winogradsky found is that the sulfur was essentially food for the Beggiatoa, fueling their cellular respiration.

维诺格拉茨基， 实际上贝氏菌的食物，为其细胞呼吸提供能量。

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

称为细胞呼吸的过程消耗葡萄糖和氧气以形成 ATP，即细胞的能量货币。

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， 即用于产生能量的碳水化合物，会经历一个称为细胞呼吸的过程。

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，因此产生二氧化碳。

But as scientists better understood the importance of oxygen to cellular respiration, some began to wonder if Spallanzani was wrong.

但随着科学家们更好地理解了氧气对细胞呼吸的重要性，有些人开始怀疑拉扎罗·斯帕兰扎尼否错了。

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 柠檬酸，它包括人类在内的哺乳动物细胞呼吸过程中产生的，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.

只有通过协同工作，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过程成为可能。

When we breathe in, our blood takes oxygen out of the air through our lungs and carries it to our cells where it's used in the process of cellular respiration.

当我们吸气时，我们的血液通过肺部从空气中吸收氧气，并将其输送到我们的细胞中，在那里用于细胞呼吸过程。

Oxygen does play a crucial role in one of the last steps of cellular respiration, but luckily our bodies have alternative pathways that help us survive when we temporarily lack oxygen.

氧气确实在细胞呼吸的最后一个步骤中起着重要的作用，但幸运的我们的身体内存在着交替途径，可以帮助我们在临时缺氧的情况下活下来。

Cellular respiration occurs in three simultaneous phases, where glucose is broken down by glycolysis and other catabolic reactions; and then turned into pyruvic acid and acetyl CoA; and finally ushered into the Kreb's cycle.

细胞呼吸生在三个同时的阶段，其中葡萄糖被糖酵解和其他分解代谢反应分解；然后转化为丙酮酸和乙酰辅酶 A；最后进入克雷布循环。
