Oxidation States, Photosynthesis and Hess’s Law
Peter Mander
OK so here’s a different way of illustrating the Calvin Cycle, the light-independent sequence of reactions in photosynthesis. There are no molecular representations, no long chemical names. Instead, this cycle shows the number of carbon atoms in the input, output and cycle intermediates, together with their average oxidation states and the number of molecules present. The key at top right is your guide. The numbers inscribed in blue show the changes in oxidation state of the intermediates and...
