摘要
对菠菜类囊体膜的亚微结构和功能进行了初步研究。结果表明,在基粒和间质类囊体膜上,分布着一些具有PSI活性、直径为8～14nm的膜颗粒,位于基粒类囊体的EF面,分布着较大的,且具有PSⅡ活性的膜颗粒。分布于ES,EF和PF面上的PSII膜颗粒的直径分别为15nm,12.5 nm和14nm,并呈正态分布。
This paper studied the supramolecular structure and function of spinachthylakoid membranes particles. Those ranging 20~100 nm in their diameter havethe function of PSI and those with diameter of 100~500 nm have the function ofPSII. The supramolecular particles with their diameter of 8~14 nm on the granaand stroma thylakoid membranes with the function of PSI. The PSII supramole-cular particles present Gauss distribution at centers of 15 nm. 12.5 nm, 14 nm onES, EF and PF face respectively.
