为什么成熟红细胞无线粒体,却能在无氧环境下长期存活,且不产生乳酸以外的代谢废物?
Why do mature red blood cells lack mitochondria, yet can survive for a long time in an anaerobic environment and produce no metabolic waste other than lactic acid?
(AI生成)(generated by AI)
成熟哺乳动物红细胞无线粒体只能进行无氧糖酵解供能,代谢途径单一仅生成乳酸,且细胞膜可及时将乳酸排出胞外避免堆积中毒,因此能在无氧环境中长期存活且只产生乳酸一种代谢废物。
Mature mammalian red blood cells, which have no mitochondria, can only perform anaerobic glycolysis for energy. Their metabolic pathway is simple and produces only lactate, and the cell membrane can promptly expel lactate outside the cell to avoid toxic accumulation. Therefore, they can survive long-term in an anaerobic environment and produce only one type of metabolic waste: lactate.
