Now your hemoglobin is known as oxyhemoglobin, or HbO2.

现在你的血红蛋白被称为氧合血红蛋白，或 HbO2。

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

血红蛋白与氧结合形成氧血红蛋白的过程称为负载。

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，氧气被加载到血红蛋白上，形成我们所谓的氧合血红蛋白。

Unloading refers to the removal of oxygen from the oxyhemoglobin.

卸载是指从氧合血红蛋白中除去氧。

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

几乎所有的氧气都是以氧血红蛋白的形式在我们的红细胞中运输到全身。

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，氧气从氧合血红蛋白中释放出来，形成了我们所说的脱氧血红蛋白。

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，氧合血红蛋白就会随着氧气的释放而释放，并扩散到血浆中，最终扩散到我们的细胞中。

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

氧从血红蛋白中释放出来，扩散出红细胞并溶解在血浆中。

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

肺中高浓度氧气将反应推向右侧，因此有利于负载并形成氧合血红蛋白。

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与脱氧血红蛋白的结合比与氧血红蛋白的结合更容易。
