oxygenated

One of the important components of all living organi*s is the need for oxygen, and the reason we need oxygen is that we use oxygen to essentially generate energy so that we can live.

生物所具有的共同特点之一是 对氧气的需求 我们需要氧气产生能量 维持生命

Actually, decomposition requires oxygen, and there's no oxygen in space.

其实得有氧气才能腐烂 而太空中没有氧气

Unlike our blood, which is oxygenated by iron, theirs is oxygenated by copper.

跟人类的血液被铁氧化不同的是 它们的血是被铜氧化的

So this is haemoglobin containing oxygen and this is haemoglobin that isn't bound to very much oxygen.

这边是结合了氧的血红蛋白 而这边是没有结合很多氧的血红蛋白

And we have an apparent serious oxygen leak in the cryogenic oxygen in the ervice module.

很显然是冷冻液氧罐里的 氧气发生了泄露

We have to first convert the liquid oxygen into gas because our lungs need gas oxygen.

我们首先要将氧气从液态 转换为气态因为我们的肺需要气态氧

We had the intercom going all the time though, checking the men with the oxygen masks on, make sure their oxygen was flowing right.

我们只有用内部通话装置 去确认大家都带上了氧气面罩 以确保他们的氧气能够正常流通

And what he did he was the first ever to do this is that he jumped from 30,000 feet, which in and of itself is a big deal because you need oxygen masks to be able to carry enough oxygen.

他当时正在做的是世界上从没有人做过的 从9144米的高空跳下 这本身就非常了不起 因为在高空你需要氧气面罩来输送足够的氧气

Divide that by 13, each consuming 1.5 cubic feet of oxygen per hour, we have one hour and ten minutes of oxygen left.

除以十三 每人每小时要消耗42.5立方分米的氧气 我们还剩一小时十分钟的氧气

And the shape of haemoglobin is so important because when one molecule of oxygen binds to the haemoglobin protein, it actually changes the shape and that encourages more molecules of oxygen to bind.

血红蛋白的形态十分重要 因为当一分子氧结合到血红蛋白上 实际上这会改变其形态 以便于结合更多的氧
