Electron Flow in Photosynthesis

 

Tested Studies in Laboratory Teaching, 1989, Volume 10

Abstract

The fascinating concept of electron flow is explored with simple equipment in an exercise for first-year students. Students use a spectrophotometer to generate an absorption spectrum for spinach chloroplasts, and then make a prediction about the effect of wavelength of light on the rate of photosynthesis. Students design their own carefully controlled experiments to test their predictions.
