An immature form of these cells expresses CD71 on their surface. (10[1])The function (-5[1])of these non-kidney cells depends on AE1, which exchanges chloride and bicarbonate ions. (10[1])Reticulocytes (10[2])must undergo organelle expulsion before maturing (10[1])into these (10[1])cells. (10[2])These cells can release (10[2])ATP (10[1])when subject (-5[1])to vigorous flow. (10[1])Decreasing carbon dioxide concentration (10[1])greatly (10[1])increases (10[3])the (10[1])efficiency (10[1])of these (10[2])cells (10[1])according (10[2])to the Bohr (-5[1])effect. (10[5]-5[2])These cells assume (10[2])a biconcave (10[1])disk (10[2])shape (10[7])to (10[1])allow (10[2])for (10[1])a high (10[2])surface-area-to-volume (10[7])ratio (10[1])to facilitate the diffusion of gasses. For 10 points, name these hemoglobin-rich (10[1]-5[1])cells (10[1])that transport oxygen to tissues (10[2])through the (10[1])circulatory system. ■END■ (10[4])
