Can anybody explain.. in simple and memorable terms what the heck the
Light Stage(/Light-Dependent Stage) and the
Dark Stage(/Light-Independent Stage) is about!? {
Photosynthesis}

I'm finding it really difficult to get my head around it.
Same goes for
Glycolysis and the
Krebs Cycle. {
Respiration}
Apparently a question on either comes up every year: This worries me..
since I don't understand it very much.
Any help would be appreciated!!
Thankoop. (:
