primary lysosome

Autophagy is an important physiological processes occuring in eukaryotic cells by primary lysosome treating cell endogenous substrate , by which life maintains protein metabolism balancing and intracellular environment stable .

自噬是发生在真核细胞中由细胞初级溶酶体处理内源性底物的重要生理过程，生命体借此维持蛋白质代谢平衡及细胞内环境稳定。

Stage ⅳ, the spermatid and acrosomal complex was well developed . The nucleus condensed into the largest extent , but the Golgi complex degenerated into primary lysosome .

时期Ⅳ，精子发育成熟，核浓缩到最大限度，顶体发育完全，高尔基体退化为初级溶酶体。
