A chemical equation for photosynthesis?
6 H2O + 6 CO2 → 6 O2 + C6H12O6
(A) Do carbon atoms become oxidized or reduced during photosynthesis?
(B) Are the carbon atoms moving to a higher or lower energy state during photosynthesis?

(A) Reduced. Carbon gains electrons
Find oxidation number of C in both compounds mathematically
CO2: C + (-2x2) = 0 --> C = +4
C6H12O6: (6C + (12x1)+(-2x6) = 0) --> C = 0
4 --> 0 (means gained 4 electrons)
... or you can use the fact that C's on CO2 gained hydrogen and electrons
(B) Higher. It stores more potential energy as glucose.
