Order and Kinetics
The overall process of photosynthesis takes place in four stages:
| Stage | Description | Time scale |
|---|---|---|
| 1 | Energy transfer in antenna chlorophyll (thylakoid membranes) | femtosecond to picosecond |
| 2 | Transfer of electrons in photochemical reactions (thylakoid membranes) | picosecond to nanosecond |
| 3 | Electron transport chain and ATP synthesis (thylakoid membranes) | microsecond to millisecond |
| 4 | Carbon fixation and export of stable products | millisecond to second |

Famous quotes containing the word order:
“Knowing what [Christ] knew , knowing all about mankind—ah! who would have thought that the crime is not so much to make others die, but to die oneself—confronted day and night with his innocent crime, it became too difficult to go on. It was better to get it over with, to not defend himself, to die, in order not to be the only one to have survived, and to go elsewhere, where, perhaps, he would be supported.”
—Albert Camus (1913–1960)
