Chapter 10, Problem 7

Apply what you know of the relationship between the light-capturing reactions and the Calvin cycle to calculate the number of photons used to produce a new G3P and regenerate RuBP. (Assume 1 ATP is produced for each pair of electrons used to form NADPH.)

Video transcript

Hi everyone. Let's look at our next problem here. It says how many photons of light are used to produce six oxygen molecules during photosynthesis? Well, during photosynthesis, eight photons of light are required to produce one molecule of oxygen. So in that case, if we are looking at six oxygen molecules then For each molecule, auction eight photons, so eight times six Will Equal photons. So our answer is choice D 48 Photons of light required to produce six oxygen molecules. That was a nice, easy one. So, we'll see you in the next video.
