Fluctuating light

referring to the photosystems.gif

takes time for Calvin Cycle to get up to speed

excess goes to H2O2

fluctuating light results in higher H2O2

 

3 min light: 3 min dark

offest of 0.41 uM [O2]

1 min light: 1 min dark repeated 3 times

offset of 0.62 uM [O2]

PvsE curves can be augmented by also looking at the the transients between light and dark
