Figure 1. (a) Electron micrograph of an isolated chloroplast. The chloroplast is delimited by a double envelope (CE) membrane. Inside is the stroma (S) containing the thylakoid membrane. The thylakoid membrane is highly folded, forming granal stack regions (GS) interconnected by stromal exposed membrane regions.
(b) Schematic of the thylakoid membrane showing the major protein complexes and associated cofactors. |
