Explain how red blood cells take up oxygen, and how they transport it to respiring cells. [3] 相关知识点: 试题来源: 解析 红细胞通过一种叫做血红蛋白的特殊蛋白质来摄取和运输氧气。血红蛋白分子内部含有铁离子,这些铁离子可以与氧气分子结合。当红细胞流经肺部时,由于肺泡中的氧气浓度较高,氧气分子会...
a. How are red blood cells formed? b. What factors regulate their formation? Explain the development of the blood cells and how they are differentiated from a common progenitor cell. Be sure to include all the leukocytes and the erythrocytes. ...
In this process, the iron in haemoglobin is recycled for use in new blood cells and the hem molecule is degraded, conjugated to bilirubin, and eliminated from the body. All the other cellular proteins are either recycled or eliminated. Historically, this process was thought to occur exclusively...
Blood vessel with an erythrocyte (red blood cell, E) within its lumen, endothelial cells forming its tunica intima (inner layer), and pericytes forming its tunica adventitia (outer layer) Credit: Robert M. Hunt/Wikipedia/CC BY 3.0 Researchers at Heidelberg University have discovered a crucial bi...
red blood cells, And a sorting step of sorting the nucleated erythrocytes into nucleated red blood cells derived from the mother and nucleated erythrocytes derived from the fetus based on the spectroscopic characteristics resulting from the oxygen affinity of hemoglobin of the red blood cells and the...
Red blood cells are also known as erythrocytes. They are biconcave in shape, which is an adaptation for the red blood cell?s function of transporting gases. Mature red blood cells lack nuclei, so they cannot synthesize proteins or divide....
“Blood cell adhesion is indeed a very complex process, and we had to develop new models based on such microfluidic experiments. These adhesion experiments and corresponding simulations for sickle red cells under hypoxia are quantitative and unique,” says George Karniadakis, a professor of applied ...

"It's all red." Well it's not as simple as you might think. Blood is made up of different parts such as red blood cells (红血球) white blood cells and platelets (血小板). Two chemical molecules (分子) on the red blood cells make people's blood different. Scientists mark one ...
