成熟的红细胞没有细胞核、线粒体和核糖体,因此,也就不合成蛋白质或进行氧化磷酸化。尽管红细胞的代谢能力有限,它仍能在血循环中生存大约120天。为了维持其正常的圆盘状,进行阳离子的主动转运,维持腺嘌呤核苷酸的补救途径以及为了合成谷胱甘肽,红细胞必须利用三磷酸腺苷(ATP)。大约有1％的循环红细胞是网织红细胞,这些红细胞有线粒体和核糖体。能够通过氧化磷酸化产生ATP。
Mature red blood cells do not have nuclei, mitochondria and ribosomes, and therefore, no protein synthesis or oxidative phosphorylation. Despite its limited metabolic capacity, erythrocytes survive in the bloodstream for about 120 days. In order to maintain its normal disc shape, active cations are transported, adenine nucleotide maintenance pathways are maintained, and red blood cells must utilize adenosine triphosphate (ATP) for the synthesis of glutathione. About 1% of circulating red blood cells are reticulocytes, these red blood cells have mitochondria and ribosomes. ATP can be produced by oxidative phosphorylation.
