Now your hemoglobin is known as oxyhemoglobin, or HbO2.

现在你的血红被称为氧合血红，或 HbO2。

The process by which hemoglobin binds oxygen to form oxyhemoglobin is called loading.

血红与氧结合形成氧血红的过程称为负载。

As blood flows through the lungs, oxygen is loaded onto hemoglobin, and that forms what we call oxyhemoglobin.

当血液流经肺部时，氧被加载到血红上，形成我们所谓的氧合血红。

Unloading refers to the removal of oxygen from the oxyhemoglobin.

卸载是指从氧合血红除去氧。

Almost all of this oxygen is transported throughout the body in our red blood cells in the form of oxyhemoglobin.

几乎所有的氧都是以氧血红的形式在我们的红细胞运输到全身。

As blood flows through the metabolizing tissues, oxygen is unloaded from the oxyhemoglobin, forming what we call deoxyhemoglobin.

当血液流经代谢组织时，氧从氧合血红释放出来，形成了我们所说的脱氧血红。

Once in the metabolizing tissues, oxyhemoglobin is unloaded as oxygen is released and diffuses into the plasma and ultimately our cells.

一旦进入新陈代谢的组织，氧合血红就会随着氧的释放而释放，并扩散到血浆，最终扩散到我们的细胞。

Oxygen is released from oxyhemoglobin, diffuses out of the red blood cell and dissolves in the plasma.

氧从血红释放出来，扩散出红细胞并溶解在血浆。

The high concentration of oxygen that exists in our lungs pushes the reaction to the right, thus favoring loading and the formation oxyhemoglobin.

肺高浓度氧将反应推向右侧，因此有利于负载并形成氧合血红。

While it seems the cell is mainly interested in making ATP, 2,3-BPG serves a purpose as well. 2,3-BPG binds to deoxygenated hemoglobin more readily than it binds to oxyhemoglobin.

虽然细胞可能主要对制造ATP，但2，3-BPG也有作用。2，3-BPG与脱氧血红的结合比与氧血红的结合更容易。
