The chloroplast envelope — barrier or bridge?

Resumo

O envelope do cloroplasto é uma barreira altamente eficaz contra o movimento unidirecional da maioria dos cátions e ânions. Ainda assim, em células de folhas iluminadas, há uma rápida troca de metabólitos aniônicos entre os cloroplastos e o citosol, o que influencia profundamente o metabolismo extracloroplástico.



Abstract

The chloroplast envelope is a highly effective barrier against the unidirectional movement of most cations and anions. Still, in illuminated leaf cells there is a rapid exchange of anionic metabolites between chloroplasts and cytosol which profoundly influences extrachloroplast metabolism.
